They look like they're medals, not coins. The top one appears to have a lot of rim damage. I hope you didn't buy them already. Chris
It's hard to tell about a couple of them from your photos, but the larger ones should be given a decent burial. Chris
If you don't know what you're doing, you shouldn't attempt to clean any coin or medal. You will only decrease its value. Chris
