[Solved] 1976-s 25cent bicentennial issue series 39pr, coin 30
Looking for value of this coin and i have as well 2002-s and 1978-s
I believe this is the CLAD-proof variety, right? Or do you have the silver-proof variety with 40% silver content?
Since there are regular copper-nickel clad-proof coins as well, you'll need to check the edge of the coin. If you see it has a reddish or brownish stripe around its circumference, like all US dimes and quarters in circulation then it's clad-proof. However, if it has a light gray stripe, then it's a 40% silver coin. In case, it is all the same color with no visible stripe someone may have plated the coin.
Clad-proof coins go from a few tens of dollars to a few thousand, but that depends on the market trends, grade, etc. Here you can see some of the sold price ranges - https://www.pcgs.com/coinfacts/coin/1976-s-25c-clad/6007.
You should probably consult with some reputable coin dealers and appraisers such as PCGS and NGC if you are interested in finding out the actual price tag on your coin.
You are welcome @turysta glad that I can help at least a bit. Fingers crossed that your coin gets a good price!
