Greetings all - so I'm wondering if silver coins, will scratch silver coins of the same purity/composition. Strange-sounding question probably, but I just started getting back into coins, and just bought a roll of Peace dollars online. Unfortunately they weren't packaged as well as they should have been, they fell out of the plastic tube and were banging around in the box when they arrived. Luckily they were circulated - I bought them mainly for the silver value - so no issue of AU/BU coins getting ruined. I have photos of the coins from the auction, and photos of the actual coins after being received - they look OK as far as I can tell, but it's hard to tell (I live overseas and a family member received the coins, I won't be able to see them in person until the next time I go there for a visit). So, your opinions? I've read that a metal can scratch the same metal, but it's difficult. Thanks Edited by krem1234

 Sorry that your coins weren't packaged properly. Perhaps you can return them to the seller.  |

Identical coins that are jostled together produce...normal coin wear. They would eventually wear down to nothing, a combination of scratching, rubbing and gouges.

Yes. That is how we got 11 (theoretical) grades of uncirculated coins. They were stored in the mint bags.

OOPS, How rude of me I forgot to You to the forum  All coins of equivalent size and metal composition will scratch each other even a rub with a soft cloth will mark most coins. Edited by trout1105

Hardest material of all:
The various grades of diamond dust is the only material that is used to cut and polish diamond facets.
Steel is a very useful material. It can be hardened to cut softer steels, as in a lathe. The finished job can then be hardened.
Mints make use of this property of steel, when making coinage dies.
Thus various steels can have a Moh's range of between 7 and 8, but
steel hardness is measured in the Brinell Scale, where a tiny cone is pressed into the test object, and the depth of the dimple is measured.

I am also on a yes making knifes as a hobby I harden them to about a 65 rock well hardness and then polish them to a mirror polish, even very soft metal will scratch it even though it's so hard, the steel I use is much harder than s30v and contains vanadium cobalt and tungsten among other things and the carbon is 1.5% so it's pretty hard stuff!
any softer metal will leave a scratch even if you just pull it softly over it

Thanks guys, that's what I figured. I'll probably keep them as they were well-circulated to begin with, and as I can't really tell whether there's any damage for sure comparing the auction photos with how they look now. The seller was kind of an butt about it, he apologized but kept saying "well they're worth their silver value, so scratches don't matter" - I said OK, but there's a reason why people don't throw a bunch a coins into a box or a padded envelope when shipping them. No one wants to receive a box of loose coins regardless of the situation.
