What is a good condition sheet of Project Mercury 4 cent stamps worth beyond the 2 dollar face value?

Answer 1

This is a common US commemorative.

If you want to buy just one it will probably cost you from 10 to 25 cents at a stamp store for a mint or used copy

If you want to order it by mail, you would have to pay postage and handling in addition.

Dealers get them as part of larger lots for almost nothing per stamp- say 65% face if mint and 1/2 cent if used.

It is the kind of stamp I use on letters if unused or give to kids if used.

Answer 2

When I list them on eBay, I usually get $3.95 per full mint sheet of 50.

Answer 3

Dealers might give you 80 percent of the face value for the stamps. You'd be better off to use them for postage.
