DBM Pillar of the Community Canada 9865 Posts	Posted 11/17/2011 11:27 am I saw your coins in the metal detecting section.They probably were toned by the steroids leaching into the soil of the football field,or the chemicals used to keep the field nice and green. Report this Post to the Staff

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 11/17/2011 2:48 pm For MD coins, any toning would be highly dependent on local soil conditions and chemical compositions. Most MD coins turn out to be dark(black, brown, or grey), crusty, and corroded. Report this Post to the Staff
