how much are morgan silver dollars worth from 1878-1888 and 1890, 1901.1902 &1921?

You have too many to give prices on. They made quite a few from 1878-1888. You also did not list if they had mint marks or not. It is on the reverse (Eagle side) at the bottom under the wealth. I can tell you that who ever bought them paid too much. You buy coins from coin dealers not magazine sellers. The prices through any of them as well as TV shopping channels, are way out of line in price, to the real world of collecting. Your best bet is to see a couple of local coin dealers for they can grade the coins, then make an offer. If given all the info and there are just a few coins I can come up with a ballpark figure. It is too time consuming to do a lot of coins this way.
