I finally got around to weighing the 90's & 2000's Kennedy proofs so that I am sure which are the clads & which are the silver proofs. The silver proofs weigh 12.6g & the clads 11.3g. I also use the Kleenex trick, It works too. Do these weights agree with you guy's?
Silver issue (regular circulation in year 1964, silver proof sets from 1992 to date): 12.5 Silver-clad issues (regular circulation in years 1965-1970, proof set in years 1975-1976): 11.5 Don't forget the Copper-nickel clad issues (regular circulation from 1971 to date): 11.34
more Kennedys I have put together a small run of PR &MS-65-67 cameo 1964-1969-s in my photo galley check the out
