Personally...I would say 1872, which is also the only Gothic I ever saw in circulation, but if date is irrelevant, just wait and see what comes up. In my opinion though, the earlier portrait (the change happened in 1879) is the nicer. A similar portrait, although completely different lettering appeared on the 1849 'Godless' florin and these are relatively common in high grade, so may be a best buy.
