There is a gentlemen doing business in Colorado that makes amazing reproductions of US coins. Even though his copies are exquisite, he gets away with not affixing the word COPY anywhere on his coins because he creates Fantasy pieces. I own two of his Peace Dollars, one dated 1918 and one dated 1965. The 1918 is in high relief (like the 1921) but also includes the infamous broken sword that caused so much controversy before the Dollar was released. The 1965 Dollar is obviously meant as an homage to the fabled 1964 Peace Dollar, but is given a fantasy date so as not to run afoul of the actually minted 1964 version.
Mr. Daniel Carr, the creator of these pieces, takes pains to overstrike these fantasy pieces on genuine Peace Dollars. Mr. Carr does this same thing with Morgan Dollars (he has produced a 1964 Morgan) and with a large variety of other US coin types. I also own his 1858 Braided Hair Large Cent, overstruck on a genuine Large Cent of the era and a club medal struck for the Colorado Springs Numismatic Society, which was overstruck on a 1976 D CN Eisenhower Dollar. You can even see the outline of Eisenhower on the Obverse, it kind of reminds me of clashed dies. So bottom line, Mr. Carr is prodigious and his efforts sell well on his website as well as on Ebay.
I happen to like his products, I am glad he is able to skirt the Copy law, I am assuming, since he only produces fantasy dates, no one can ever be fooled. What do YOU think?
