Pin trading question

[JackSparrowGa]

In advance of our trip I went on eBay to buy some less expensive pins for my son to trade. I won a lot of ten, but now in looking at them they are mostly ProPin Germany pins. Is this OK? Are they tradeable with the CM's? Thanks for any input.

OOPs, I guess I should have scanned the board before posting, seems this has been discussed at length already. Sorry.
