Used on cover
I have been lucky enough to acquire a cover with a pair of 2d blue plate 9 (T-J, T-K) with the J & C Boyd underprint.  Obviously you will have to take my word for it, being an underprint and all!

A single perfin has provisionally been identified with J. & C. Boyd & Co.

See the Philatelic Links and References page for more information on Perfins.

The above underprints should not be confused with the overprint applied to stamps the firm used for receipt purposes.  These stamps were overprinted with the words RECEIVED FOR J. & C. Boyd and Co.
