General Comments

1851 is a major key to the Liberty Seated Dollar series. Only 1,300 were minted. None were released at the time of mintage. The gold dollar, with a large mintage total in 1850 and much greater totals in 1851, 1852, and 1853, had become the coin of choice for trade. The 1851 silver dollars were apparently used as exchange for silver bullion as the need arose, and probably left the mint over the next few years. At 1,300 the mintage is low by any standards. It ranks 6th out of the 47 Liberty Seated Dollar issues. Of the five coins with lower mintages one, the 1873-S, hasn’t been confirmed to exist, and two, the 1866 no motto and 1870-S, are virtually unobtainable for the average or even the serious collector. Only the 1852 and the proof-only 1858 are within the reach of the collector with an above average pocket book. Business strike examples are available at most a few times each year, usually as part of major auctions. We noted a total of 24 offerings of business strikes in Heritage auctions since 2000, representing 17 different coins.

1851 silver dollars are truly rare in all grades. The highest currently graded business strikes are two MS65 examples, one graded by PCGS, the other by NGC. PCGS has graded five coins MS64. NGC has graded 2 in that level. At the MS63 level PCGS has graded two coins, NGC nine. It’s probable that these 20 choice mint state records represent at most 12 to 15 coins. PCGS has graded an additional 11 coins in grades MS60-MS62. NGC has graded 6 in that range. In circulated grades the pickings are even more difficult. PCGS has graded only 16 coins below mint state. Only 4 are below AU – one VG8, one VG10, and two XF45. NGC has graded only 6 below mint state, all AU’s. The collector developing a set at the XF or lower level has a choice between waiting possibly many years for a single opportunity to obtain the date or filling the hole with a higher-grade coin. Population statistics are as of February, 2017.

1851 business strikes are usually well struck. Star centrals and hair detail are well defined. Some examples show slight weakness on the top of the eagle’s left wing. High-grade business strikes are sometimes semi-prooflike, but more often frosty. Fully prooflike examples are rare. It’s hard to be picky about the strike and surfaces when looking for this date, as nice examples are seldom seen in any grade.

1851 Proofs

1851 proofs deserve a separate discussion. Original 1851 proofs may not exist. We believe that it’s probable that one or two examples exist, but none have been confirmed. We’ve identified the original proof as die marriage OC-P1, and left a place for it in our listings. If these exist the obverse might be the business strike obverse, Obverse 1, but more likely one of the two known proof obverse dies, or possibly a currently undocumented proof obverse. The obverse would almost certainly be paired with Reverse 1840 PA. Confirmed proofs paired with this reverse exist for every year from 1840 through 1854 except 1851 and 1853, and we believe that all are originals.

The 1851 proof examples normally seen are restrikes. Estimates of the proof restrike mintage vary from 50 to 100. We believe that the correct estimate is probably around 75, with about 60% of those surviving today. The finest known 1851 restrikes are two coins graded PR65 Cameo, one by PCGS and one by NGC. The PCGS example, the Kaufman coin, was originally in an NGC PR66 Cameo holder, but is now graded PR65 Cameo by PCGS. This coin is an example of the OC-P3 die marriage. Each grading service lists one additional coin at the PR65 level. PCGS shows four additional coins graded PR64. NGC shows one at that level. The grading services list a total of 48 coins currently graded, 30 at PCGS and 18 at NGC. At least a dozen of these grading records surely represent re-submissions. Population statistics are as of February, 2017. 1851 proofs are usually found well-struck, with all design elements sharply defined. Cameo contrast is common on all proof restrike die marriages.

1851 proof restrikes have been known since the 1860’s, although at that time they were not necessarily considered restrikes. As time passed more research was done, and more was learned. Walter Breen, in his epic encyclopedia of U. S. proofs (Reference 7) identified a single obverse die, and mentioned that multiple reverse dies may exist. David Bowers (reference 4) identified two die marriages, with two different obverse dies each paired to a unique reverse. His descriptions of the obverse die markers were excellent, although one detail, the unfinished area under Miss Liberty’s chin, or “beard”, was attributed to the wrong obverse. Most literature has speculated, based on circumstantial evidence only, that restrikes were created in the 1858-59 timeframe, and again in 1865-1867.

Why were the restrikes created? Based on letters documented in references 4 and 16 it’s clear that mint officials wanted examples of rare dates both to sell to collectors and to trade to collectors for coins and medals needed to expand the mint cabinet. Collectors of that day weren’t particularly interested in business strikes. They wanted proofs. The 1851, with an original proof mintage that was either tiny or non-existent, qualified as a rare or possibly unavailable date, and thus was an obvious restrike candidate.

Based on our analysis of 1851 dies we can confirm that 3 different restrike die marriages were created, using 2 obverse dies and 3 reverses. None of these dies were used for business strikes. The first die marriage, our OC-P2, pairs our obverse P2, the one referred to as obverse 2 by Bowers, with the reverse die used to strike original proofs in 1856, 1857, and 1858. The second die marriage, our OC-P3, also uses our obverse P2, pairing it with the reverse die used to strike all 1859 original proofs. The third die marriage, our OC-P4, pairs our obverse P3, the one referred to as obverse 1 by Bowers, with the reverse die used to strike almost all 1865 original proofs. All these die marriages are described in detail later in this chapter.

Our estimates of when the restrikes might have been created are based on the same circumstantial evidence others have used, but aided by our having identified the specific reverse dies that were used for each restrike. The 1851 restrikes were minted in two, possibly three timeframes. The first restrike, our die marriage OC-P2, mated a new or at least previously unused obverse die, our Obverse P2, to Reverse 1856 PA, the die previously used to strike original proofs from 1856, 1857, and 1858. The timeframe for this striking is simply an educated guess. We believe that they were struck in late 1858 or early 1859, after the reverse die was used to strike 1858 originals. Examples of this die pair are extremely rare. The only example we’ve confirmed is the coin sold by David Lawrence Rare Coins as part of the Richmond collection.

The second restrike, our die marriage OC-P3, paired Obverse P2 with Reverse 1859 PA, the reverse die used to mint all 1859 proofs. We believe that they were minted in late 1859 or early 1860. We identified the timeframe for their striking by noting that Reverse 1859 PA wasn’t carried over to strike 1860 proofs, so we assume that it was retired soon after its use in 1859, and would only have been available for a short period.

The third restrike, our die marriage OC-P4, mated a new or at least previously unused obverse die, our Obverse P3, with the reverse die used to strike almost all 1865 proofs. We believe that they were minted in late 1865 or early 1866, Again we identified the timeframe for their striking by noting that Reverse 1865 PA wasn’t carried over to strike 1866 proofs, so we assume that it was retired soon after its use in 1865, and would only have been available for a short period. Another factor that supports this conclusion is the change that occurred in 1866, from the NO MOTTO reverse to WITH MOTTO. Additionally, we note a record that the first sale of a copper 1851 dollar, J-132, was in October, 1865 (reference 16). This pattern used the same dies as our OC-P4 die marriage.

1851 Die Marriages

We’ve confirmed a total of 4 die marriages for 1851, 3 of them proofs. A fifth die marriage is possible if the original proof exists. We’ve left a place in our die marriage listings to accommodate this possibility. The following table summarizes the known die marriages.

A single pair of dies was used to strike all business strikes. We’ve identified the business strike die pair as OC-1. Neither die was used for proofs. The obverse is known as the “high date”. The date position is much higher in the field than either of the proof dies, and slants slightly down to the right. Almost all examples seen exhibit light obverse clash marks in the field under Miss Liberty’s arm. The dies apparently clashed very early in the mintage. Unclashed examples are seldom seen. The reverse die was originally used to strike 1848 business strikes, and was re-used in 1849 and 1850. The die is almost certainly clashed in most of its 1851 usage, but the clashing is very light. A vivid imagination is required to detect it.

The original issue 1851 proof is unconfirmed. Restrikes were minted in three different timeframes. They mated two different obverse dies, neither used for business strikes, with reverse dies that were first used for regular issue proofs in later years.

1851 Business Strike Emission Sequence

With only a single die marriage the emission sequence isn't terribly interesting.

1851 Proof Emission Sequence

We assume that the original 1851 proof, if it exists, is the first issue. The 3 restrikes were placed in the emission sequence based on the original timeframes of reverse die usage. The degradation of the obverses during their use wasn’t sufficient to conclusively confirm the emission sequence.

Emission Order

Die Marriage


1 OC-P1 If it exists this is the only original proof die marriage.
2 OC-P2 This die marriage uses the reverse die first used for original proofs of 1856, 1857 and 1858.
3 OC-P3 This die marriage uses the reverse die first used for original proofs of 1859.
4 OC-P4 This die marriage uses the reverse die first used for original proofs of 1865.

1851 Quick Finder Chart

1851 die marriages are easy to attribute. The only dies that are difficult to differentiate are Obverses P2 and P3. With each married to a different easy-to-attribute reverse they don't present a problem.
