I have been working on this uncleaned lot for quite sometime. The first picture is from June of this year when I was able to clean off enough dirt to reveal details in attempt to ID this coin. Any suggestions on further cleaning measures or should I stop? They have soaked in olive oil for quite sometime and today I picked at it with good results. Suggestions on exact ID would be awesome. The reverse appears to be a Reclining River god or Nymph from Thrace, possible autonomous coinage of Odessos? Maybe c. BC. 270-250, maybe a smaller version of Sear GCV1680 ?
