What is the value of a Reggie Jackson 23K-gold stamp?

Answer 1

Note that these stamps have value only to collectors of sports memorabilia. The gold value is extremely minimal and not enough to make it worth while to invest in as a precious metal. It was not issued by the US Government, so has no value to a philatelist. You can purchase these for around $20 or so, to sell them you would be lucky to get half that.

Answer 2

Back when the stamp was produced it was only $2.00, but now the most expensive is about $30.00.
