I note that above you said, "Condemnation only due to
style and unpublished dies and sold by
fake seller is error-prone." These are, however, precisely the most useful and likely methods of detecting
fakes from modern dies. I don't agree that it is especially error prone. If we have all three elements, we can usually feel very comfortable that the coin is fake.
Condemnation should not be only based on
style that is what I meant !
If there are other arguments too which speak for or against authentiticity they have to be considered.
The coin has to look as a whole
good or bad.
Sometimes authentic coins have been condemned due to
style which was different and from so far unknown artist or other aspects which were different from so far known authentic coins from this issue.
And some
fake coins with
very good ancient looking
style were and are considered to be authentic (but they have other problems which condemn them as
fakes, maybe impossible die links between emperors and mints and different times or pseudo
hoards from every emperor several coins but all from the same
obverse and
reverse die, or adding always the same
fakes in all new
hoards no matter if such a coins in all this
hoards make sense or not, or new pseudo
hoards which are die linked to each others but no die links to authentic specimens and so on)
There should always speak more than 1 aspect for or against authenticity and the more arguments the better and more reliable.
To "
Wreath silver medallettes", some of these were sold on
ebay by fake sellers who only sold
fakes from modern dies and so they can be coinsidered as very suspicious.
If there would not be any authentic example existing they would be
complete fantasies which would be odd but possible, forgers orientate generally on already know coins, because they will be rather accepted as authentic as so far completely unknown
types.
Completely unknown
types will be checked and suspected more than so far know
types.
But forgers do know that too and so sometimes it even speaks for authenticity that a coin is so different from all so far know because forgers try to decive and so they want to be as close as possible on original authentic coins as possible.
