Bavaria German States
John Weber of Beaver Dam, WI wrote in about a coin he could not identify. He included written legends and a photograph of the obverse and reverse of the coin, but made no mention about the metal content or the diameter of the piece.
From the legends:
With this information we can immediately surmise that this coin is from the German State of Bavaria. If we assume that it is a large silver piece and take into account the 1760 date we can best guess that John's coin is a KM#234.1, Davenport #1953, Thaler.
John's coin is very well worn, probably a VG-F, and this type is fairly common, so we would place it's approximate value right around $20 to $25.
