What is a good melt value for silver dollars and halves? I'm trying to get them at or slightly above melt. I don't care about condition, I think I'm trying to do a type set. What do you think those will cost? Thanks!
Coinflation (mentioned above) is the most convenient source; it also shows Canadian silver, and has live updates of bullion prices all day.
