If I was to buy a collection of Gold and Silver coins from someone or somewhere, how can I actually be able to tell how much it's worth in the gold/silver weight alone? I know rule of thumb that Morgan Dollars are almost an ounce of silver, but what about the rest of the coins? Is there more rules of thumb I should learn regarding this? Thanks
Are these all US coins? Usually, if it's all US coins, the 90% silver ones, and there are none involved with specific numismatic value, they get priced based on a multiple of face value. Of course that fluctuates, you can call up pretty much any coin dealer and ask them what they're paying for silver coins in bulk and they'll most likely answer with a multiple of face value (assuming they are buying silver, which most are right now).
I know older quarters, 32-64 I think, are 90% silver, 10% copper. The metal inside the quarter was worth a little over $7. If coin dealers are actually buying these silver coins for the metal content and not the coin itself, I want in. I have a small collection of some older coins, and could make more money off the metal content than they're worth in face value. I'll have to go to the bank and start asking for rolls of quarters and go through them. Although I'd be surprised if they actually left those in circulation if they knew about them...
