A couple of years back I bought a pair of Isle of Man 1839 farthings. What the seller claimed was that one of them was copper and the other bronze while Krause only list bronze mintage for the year beside proofs which this one definitely was not. On the other hand this can be simply a sign of earlier cleaning that left the coin somewhat brighter. I am wondering if anyone can share experience or reference with these? Other details worth noting are the incused W.W. (engraver Wylliam Wyon initials) on trancation. Among other things interesting is that the two A's in GRATIA are actually iverted V's however there is not a word on this in either Krause or Remick
This is a regular looking bronze coin
and this one is a brighter, possibly copper?
