i buy and sell silver all the time, so I agree with most information you have already received,, all the bullion, and silver sets, I would offer 90% of spot price, for them, the box of peace and Morgan dollars
, I would do a thorough look through for keys and semi keys, if there are none, I would offer, close to spot price, as long as they are not beaters. you will always get more than spot for silver dollars. as far as bulk, half dollars, and quarters, etc. if nothing is marked as keys, I would offer 90% of spot.. and for the cents. I would have no idea, without seeing them...
so to sum up my thoughts. you can't go wrong, if you offer 90% of spot value, for everything silver, and if there is any upside it is yours, but don't be afraid to say, this coin, or these 10 coins are worth more than that, because that goes a long way when trying to close a deal..
where dealer's may say every silver dollar is worth 18$ and you say well a couple of them are worth 22$, it may sway the deal your way..
