Just got in an red my PM's this morning and I feel your anguish 
I followed my own advice shortly afterwards and hit a BIN on a Steve Thomas BAP Auto Gold # / 10 - I just couldn't let the opportunity pass.
If it's any consolation, I've got saved scans of a few of those Potvin wins patches - so they must show up every now and again. I can't guarantee you would find one for that price with that swatch though 
Maybe it's god's way of saying you aren't meant to collect Felix Potvin and you should donate your collection to a worthy UK based cause 
I'm only playing - really feel for you, would have been nice to see that sweet card head into a deserving player collection.
