Hello, I was going threw some older sets tonight, and found some double dies. Some are listed in PCGS and a few aren't. I will list below, but my question is how much would the ones not listed be worth. Thanks Bob, 1 1963 Dime mint P it has doubleing on the front I know their are DDR denver and proof DDR but I haven't found any DDO P dimes 2 I found a 1969 .50 cent with a DDR on the lettering this is the D denver mint. 3 I found a 1961 Proof Frankin with DDR all around the lettering I see it listed on PCGS but I only see it showing the doubling on the small bird in the web site mine has it on the letters also. 4 I found a 1974 DDO Kennedy which is listed in PCGS Once again Thanks Bob,
Double dies or machine doubling add no extra value to a coin. However a 'doubled die' adds value. Without pics. of your coins, it's hard to tell what you have. See the difference; http://www.coingalaxy.com/coininfo/doubling.html
