British & English Copper Coin collecting
Rare in higher grades and can be difficult to find in any sensible grade also. The die flaw ive seen before and was used on another 1721 date with the same 1 over 0 error.
The extra tie band or ribbon does look as if it belongs there its also quite odd other areas haven’t experienced die leak, doubling or any other general defects. Farthing grades around fine.
