i recently acquired this coin as part of an uncleaned lot. the observe legend says "r dacic" which is probably "GER DACICVS" and that leads to Trajan (http://numismatics.org/ocre/results?q=obv_legendCondensed_text:*rdaci*+AND+fulltext:standing). The letters appears to be in silver plus other spots. Yet the coin has patina. Did Trajan have silvered coins or did I deciphered the legend wrong? Any help would be appreciated! Thanks, Thomas.
