I find that the 1853 Groat with date looking similar to that of the 1852 groat could well be First Currency issue with some proof's struck, later 1853 groats the date looks similar to that of the 1854 / 1855 issues.. samples I have and one that I did have show the basic 1854 type date,, ie flat topped 5 . Proof issues i thought had axis reversed ( top ^ to tail v) as I try to show from pics,,ordinary circulation issues were top ^ to Top ^ ( i think ) this is just as I see and have seen from 1 previous 1853 groat. ,, Hope this helps and not confuse,, Barrie
