Hi again Ricardo,
I have some additional info about your coin: I´m a member of the
german board (
http://www.numismatikforum.de) and moderator in the
forum for
celtic coins there and I discussed your coin with my colleague Harald, he is a specialist for
celtic coins especially for Boii and eastern
celts ... he believes, that the
weight and the
diameter is totally unusual for such a piece and also he is very sure, that this belongs not to the reference 'Velem Kapostal' I suggested yesterday, because it´s more of the
style for a variant of the
type 'Kreuzelreiter', but all of that is very uncertain ... the
weight of your coin is to low for the
diameter of 20mm too, maybe it´s an
alloy with mostly tin and only a little
part of silver, also there is no clearly reference found for the representation on obverse/reverse ... I agree to this consideration and so we are not sure if it is authentic ancient, maybe it is a (modern)
fake coin.
Best regards
Herfried
