Unfortunately the majority of CM's don't know, or don't care enough to know, much about scrappers, I have hundreds of pins, many are scrappers that were received from CM's. This is the main reason I don't pay higher prices for pins to trade, I buy from eBay but I buy from sellers I've used and have received good pins from or I use the green list on the thread linked in my signature. I'm realistic in the knowledge that I'm going to get scrappers from CM's but I don't let that stop me.
