I assume that most if not all are authentic.
We have here 1
obverse die but different die states, 2 times fresh and 1 time worn.
3 different
reverse dies 2 worn and 1 fresh.
The
reverse die statistically died earlier than
obverse dies so it is plausible to have more
reverse dies than
obverse dies.
1
obverse die on 3
reverse dies looks possible.
Forgers generally make if they cut dies by hand 1
obverse die and one
reverse die!!!!
What forgers sometimes do is that they make the same number of
obverse and
reverse dies and then mixing them.
To create this die wear forgery must have minted many hundred
fakes, so where are these
fakes?
But that forgers make 3
reverse dies on 1
obverse die is not really making sense.
They would rather make 2
obverse dies and 2
reverse dies and mixing them if they want to make die links between them.
Are you sure that there are not more die links?
If there are not more die links we have to assume that
Obverse A was used with
reverse A, till
reverse A died
Then
Obverse A was used with
revers B, till
reverse B died
And last, the last picture below
Obverse A now worn is used with
reverse C
You need to
mint, strike really many coins (several hundred or thousand) with a die/
matrix to achieve so much die wear as we see on this 2
reverse dies and the one
obverse die.
I am not convinced that artificially created die wear in modern hand cut dies with something polishing/burnishing , will even look close to real die wear from metal flow with flow lines.
Not sure how they can create flow lines artificially without hammering coins.
Modern hand cut dies = number of
obverse dies and
reverse dies is generally the same and
fakes are all from same die state (fresh dies), forgers do not
mint as many
fakes with dies as they did in ancient times.
Ancient dies, number of
reverse die is statistically higher and dies were uesed till they did so you will find coins in different die states and broken dies were replaced with new dies so you will find die links, too.
