I have a 74 half and its 11.53 grams with a specific gravity of 9.54. It pings higher pitch than its clad peers. Am I crazy to think this is a 40% planchet? Im about to spend $77 with ANACS to confirm.
Weight is gonna be the biggest factor, You can post an edge picture here, that might help. How about just taking a few photos and posting them here. Welcome to CT!
Welcome to Coin Talk. It would be great if you have a 40% silver JFK half dollar. I don't know if any have ever been found. Please post photos, especially the edge of the coin before sending it to ANACS. Thank you. I found this old Coin Talk thread but it's about a 90% half: https://www.cointalk.com/threads/1974p-90-silver-kennedy-half-dollar.164678/
I dropped it and it sounds like a 40% silver clad coin. Higher than the non silver clad. I sent it to ANACS today and I asked for the photo service. I guess ill find out in about a month or two. I will update on here. Thank you for the replies.
Unlikely to have a 40% silver planchet still in the bin 4 years later. Ring test is no measure of anything. As for the weight clads are 11.34g (yes the 40% are 11.5) but yours can be clad and still in tolerance on a slightly thicker planchet.
If it is a 1974 P I would say not it isn't, If it is a D there is a very small chance that it could be. Son Francisco sent their rejected proof planchets to Denver to be used for circulation strikes. Only CuNi clad planchets were supposed to be sent but a small number of 40% silver planchets were sent as well. The 40% bicentennial coins were being struck in 1975, and they were also striking 1974 half dollars in 1975 as well due to the date freeze, so 1974 D and 1977 D 40% silver halves and dollars are known to exist. But there is no way 40% silver planchets would have been sent the Philadelphia. And Philadelphia never struck any 40% silver half dollars at ANY time, so left over planchets couldn't be a possibility either.
