'dipped Roman contemporary forgeries'

[steve_66]

 I recently acquired a verdi gris clad Antoninus, after cleaning of the verdi gris ...da da da... copper was revealed underneath, therefor it was clearly dipped, was this a common occurrence in roman times, or is my coin some kind of numismatic rarity? thanks guys, any suggestions...ps the coin weighs less than a denarius... 

I can not upload pics due to file size limits ...but there are clear signs of delamination under microscopy....

Hi Steve,

You can reduce the pic size see Pickris' comment below:

I don't know about the coin myself but thought I would just help getting a picture up, would be nice to see

Your coin is most likely to be an 'antoninianus', which was the equivalent of the silver denarius in later Roman Imperial times. Essentially it was a bronze coin that was just washed with silver, and nowadays turn up anywhere from fully silvered to just bronze or any stage between.
