Warwickshire 1/2d Token info question

[Rob 3,002]

I've got a counterfeit 1792 Birmingham Mining & Copper Company 1/2d token here with the edge reading PAYABLL AT LONDON LIVERPOOL [  ] with the Ns reversed. The type is nominally D&H 109a, but that description gives a normal reading of PAYABLE etc. Were these edges added manually or is this a normal reading for the type with sloppy documentation? Ta.

Assume the edge was added manually, as it is incuse. So are all these edges 'unique'?
