What is the value of 20dollar gold coin with copy in the back?

Answer 1

It really depends on the year, mintmark or condition. But it is worth about $1,550 or so no matter the condition because it is 90% pure gold.

Answer 2

These coins are about 22 KT gold in fineness (90% gold and 10% copper) and weigh 33.436 grams, which yields a net 0.96750 oz of pure (24KT) gold

Answer 3

If it's a copy, odds are that it's not made of gold, and as such isn't worth much of anything.
