Hi. I'm not sure if this is the correct place to post this request, but I would like to have it notated for the West German 10 Deutsche Mark Munich Olympic Commemorative Coins that they are silver. I don't know if cataloguing them as such requires a minimum percentage of the composition to be a certain metal, but these coins are 62.5% silver. There are 6 of these coins, but they are notated as "10M", rather than as "S10M", as others show. The one example that I have submitted is 2855733-006 1972D GERMANY 10M; MUNICH OLYMPICS; ATHLETES KNEELING.
Thank you for your time.
Jason
