Hong Kong 1866 Silver Dollar

I do have some reservations regarding this coin for two reasons.

First is that the die face seems to be too small - which often happens when a die is made by casting an image from a genuine coin. If you compare the margins at the top and bottom of the obverse die to the same area on the genuine coin it appears larger. That combines with the odd looking collar seam at the top to make me suspicious of a forgery.

Second the fine detail of the Queen's crown compared to the hairline detail which is missing also makes me wonder about an image transfer process.
