I agree with Paddy that the reverse looks too deeply engraved. The bead count is the same as on an 1824, 1825 and 1829 I have images for here, so that appears to be constant from pattern through to currency. There are minor detail differences in the hair between this one and my 1825, but the hair is in better agreement with the 1824. Conversely, the profile of the earhole is a better match with my 1825 than the 1824. It's probably reasonable to assume that there were several bust punches made, all nominally the same, but needs someone to do the spadework to confirm.
An 1825 here which differs slightly in the three hair strands pointing to GR.
