to the forum and thank you for posting your coin!
While I am not an expert in this particular series, I do see a number of signs that concern me.
Compared with a known authentic Heaton example (available online at auction house archives, etc) several areas of the dragon such as snout, the shoulder of the leg below and left of the mouth, and the scales in general seem to lack detail.
Portions of the P and E in PROVINCE and C and E in CANDAREENS are missing. Portions that should not be missing from an authentic coin since there is no other evidence of a worn die, die crack, etc.
I believe it is a forgery.
