I have an complete album which dates from 1847 through 1932 - Golden Replicas of US Classic Stamps. It is in the original blue album withe approximately 100 envelopes with a 22kt gold replica stamp on each envelope and each stamp is addressed "First Day Issue" with the date of the issue. Can you tell me the value of this album?"
If the stamps are indeed gold foil, then you need to know the exact thickness of the foil (the gauge) and purity of the metal to figure out how much gold is in each one. This information may be provided with the set.
If they are gold plated on a base metal, then there is probably too little gold to even think about the melt value.
