Weigh it. If it weighs close to 5.67 grams it is clad. If it weighs close to 6.25 grams then we can talk about it.
Actually, this is not quite accurate. The government continued to make silver quarters that were dated 1964 until early 1966. Read here: http://www.usmint.gov/faqs/circulating_coins/#anchor15 The vending machine industry saw alot of growth during this era. In the early 1960s, the government falsely assumed that people were hoarding silver coins when in fact they were being stored away for long periods of time in vending machines. Their solution to people hoarding them (which wasn't a problem to begin with) was to freeze the date while they transitioned to clad.
I thought they froze the dates because of delays in getting permission through Congress. They removed the mintmarks in 1965 to try to discourage coin collectors, and also allocated out dates to not make a rarity. You are very correct collectors got the blame for this coin shortage when in fact it was Gresham's law in action.
Yup, I've gotten better looking ones than the one in this topic in much higher grade, probably why I referred to it as in "bad shape" cause well, it really looks like it is. It's definitely seen it's good share of vending machines and pockets.
Yes, I know this is an old thread. But I found a 66 quarter that "Sounds silver" I know they aren't silver after 64. It does have copper visible on the rim. My question is why does it sound like silver?
As was stated earlier in the thread, what's the weight and whats the edge look like? It's highly unlikely it's silver, but that's what you need to get an answer
