Found this object a few days ago while metal detecting. The dotted border and round shape from the border makes me believe it could be a coin. Hope someone here could help me identify it as a coin or dismiss it as a coin.
It weighs 2.66 grams. Uncertain of alloy. At first I thought it was copper, but having cleaned it i noticed a small dott of silvery color where the crust has fallen off. Take in mind it has been laying underneath clay-rich soil for probably hundreds of years, so it could be a billion of sorts.
Much appreciated.
