Nothing crazy. Just an MS-65 Full Split Band 1945-P dime. I don't know what one would bring now, but I could have had one back in the early days of Teletrade but I couldn't swing the $2K. Oh Lordy, what I could have done with money and youth. Rick L.
My thought process. Get the most-expensice coin and sell it to buy a whole bunch of coins I actually want.
The J-1776 would be a good choice, but I've always wanted a School Girl Morgan dollar. In fact there are dozens of patterns that I would like to own.
One reasonably rare trade dollar for me. I've always been afraid to invest in one fear of it being fake.
Being who I am, you would probably expect me to say, "1876-CC 20c" or "1878-S 50c" or "1870-S $1". But my choice would be the finest known 1875 $10 gold piece business strike, which happens to be AU55. There are only about 9 known examples (including two horrendously low grade examples) out of 100 originally minted. There are also 7-8 proofs which go up to 64. The business strike and proof strike are both rarer than the 1870-S $1!
