Welcome to the forum!
Scrappers and counterfeit pins are a bummer, but they do make the chase, of particular pins, more interesting. Or at least that is how I have come to terms with the issue. My wife and I have gotten better at identifying scrappers and fakes, but we still pick up a fair amount of them.
We are going to assemble a small book, as an educational reference, to help us identify these less than desirable pins. Some are quite obvious and others are merely questionable.
I guess my whole point is that we are trying not to let the fakes and scrappers ruin our pin trading fun. Just trying to turn a positive into a negative.
And, for the record, we never trade known fakes and scrappers to anyone. We take the loss and keep those things out of circulation. They remain in our keeper sets, until we find a good one, or they go in the fake/scrapper bag.
