I am no expert on U.S. Silver Dollars... and didn't put that on the coin... but... Since the 1804 Dollar wasn't actually minted in 1804, I'm not sure how it is exactly determined which is the rarest Dollar. The 1895 only had 880 coins struck and still can be found. Also, they actually found their way into circulation, whereas the 1804 dated dollar did not. Same goes for the 1893-S Morgan, which is also rare, but more were minted. RARE in the sense of the word would be the 1895 by mintage. Here's what I found: The 1804 dollar or Bowed Liberty Dollar was a dollar coin struck by the Mint of the United States, of which fifteen specimens are currently known to exist. Though dated 1804, none were struck in that year; all were minted in the 1830s or later. They were first created for use in special proof coin sets used as diplomatic gifts during Edmund Roberts' trips to Siam and Muscat. Edmund Roberts distributed the coins in 1834 and 1835. Two additional sets were ordered for government officials in Japan and Cochinchina, but Roberts died in Macau before they could be delivered. Besides those 1804 dollars produced for inclusion in the diplomatic sets, the Mint struck some examples which were used to trade with collectors for pieces desired for the Mint's coin cabinet. Numismatists first became aware of the 1804 dollar in 1842, when an illustration of one example appeared in a publication authored by two Mint employees. A collector subsequently acquired one example from the Mint in 1843. In response to numismatic demand, several examples were surreptitiously produced by Mint officials. Unlike the original coins, these later restrikes lacked the correct edge lettering, although later examples released from the Mint bore the correct lettering. The coins produced for the diplomatic mission, those struck surreptitiously without edge lettering and those with lettering are known collectively as "Class I", "Class II" and "Class III" dollars, respectively. From their discovery by numismatists, 1804 dollars have commanded high prices. Auction prices reached $1,000 by 1885, and in the mid-twentieth century, the coins realized over $30,000. In 1999, a Class I example sold for $4.14 million, then the highest price paid for any coin. Their high value has caused 1804 dollars to be a frequent target of counterfeiting and other methods of deception. As for the 1895 Morgan Proof: The most famous Proof Morgan Dollar is without a doubt the 1895. Even though Mint records indicate that 12,000 circulation strikes were made at the Philadelphia Mint none are known to exist, leaving the numismatic community with the extremely limited number of 880 proof pieces that were produced. This is neither an extremely high or low number among proofs, however because of the lack of business strikes, demand and premiums for the proof coins are high, especially for pieces that show pristine fields and cameo contrast. Once again there are also a number of circulated pieces known, which are still recognized as Proofs no matter what grade simply because no circulation strike has ever been identified of this date.
I can't afford any of those anyway. That's one of the things that I like about this forum though, differences of opinion.
He is actually a very reputable coin dealer... Very knowledgeable and reasonable prices. Dallas Rare Coins - been there 37 Years in the same location. I doubt he actually cares about selling it, by the way. He also tosses out a 1KG Bar of Gold to put in the Display Case and a 1793 Penny in VF-30 for $20K+. He's in his 70's and has had a stroke and health problems, so he doesn't advertise or go to shows anymore... Doesn't sell on the Internet as a Shop (except foreign, paper currency, and tokens that I sell for him on EBay.) He's probably Forgotten more about Coins than most people on this Forum have actually ever Learned about Coins, so please don't Discount someone with no information. FYI... My Seller Name is "DallasCoinsNThings" on EBay. AND... if you look at my later post, I examined the "Rarest Dollar" theory, and it is kind of a vague claim, but 880 Coins is the lowest mintage of Circulated U.S. Silver Dollars, even though it is a proof. SO... your claim of "False sales hype" isn't really a good description, in my opinion.
Well, the 1895 Morgan was a proof only issue, not a circulation issue. There were dollars with far lower proof mintages. Does the 1885 trade dollar not count? 5 known
