rarer than the 25 yr pennine is the first ever pennine. it was of the same design and a littl rough, with off-white enamel... i had 2 25 yr penines as they always made good swaps. i will try and post a pic of them, i think i had somewhere in region of 400.
the otterhound badges were always the most expensive, the old West yorkshire M inkhounds was a good badge, hard to get hold of
i never took the pins off, but other people often did before i bought the badges..
