1843 Obverse and date varieties
1843 A - Obv. A to An - with small date.
1843 B - Obv. A to An - with large date.
1843 C - Obv. A to An - Date: 3 over 3
1843 D - Obv. A1 (N of REGINA) tilts backwards - with small date.
1843 E - Obv. A1 to An (N of REGINA) - with large date. (As yet not found).
This large/small date variety is very difficult to spot. I hope that these pictures help.
ST 1843 A or D - With Small date
ST 1843 B or E - With Large date - All 4 numerals appear to be very slightly larger.
The back of the 3 is closer to the wreath leaves.
The 3 tilts forwards (on this example !)
* Far more difficult to find examples of large date !
ST 1843 C - Is this a small 3 over a large 3 or just a misplaced 'small' 3 repair
