If somebody wants to take the time and post a small collection on eBay, then by all means go for it. I just throw this out there because many people have like 5 or 10 coins laying around that they keep with no intention of really doing much with it. I ain't trying to make money off of this, just keep coins from being lost or melted and adding to the collection I have.
We're talking about somebody having 5 of so Buffalo Nickels, maybe a Morgan Silver Dollar, some silver Kennedy Half Dollars. If somebody wants to quickly get rid of something like this, and they went to a coin store or some place that buys silver, they will likely get whatever the spot price is on silver (no idea what that is, easy to look up). I am just offering up a separate option because I hate to see coins get melted and then are forever gone.
