I just used numista as an example, because it's the last website I went to (yesterday) that rejected me. Also their data comes from those coin catalogs, which they cite as their sources.
But I'm not telling you to collect anything, not that silver is the only type of coins. I sometimes find interesting Cu/Ni ones in my change, since I always pay for food and stuff in cash. Most people don't care about collecting this stuff, but it's a nice hobby for boring old men like me. Pic is one I'm still missing, hoping I can buy it before I get priced out of silver. I already have all their other coins on that theme.
