I will probably get flamed here...
Disney Pin Trading is NOT a cheap hobby and should not be undertaken as a hobby unless you are willing to spend the money. Does that mean you have to buy pins at full price? No, but it does mean you have to do your homework and not taint the pin trading market with possible scrappers/knock-offs. If a CM does not catch that he/she has been traded a scrapper they can unwittingly trade that to another collector (most likely a child).
One website I use frequently is
www.dizpins.com. It's a great website for editions of pins out there and even shows side by side comparison of known scrappers with legitimate pins. They also offer up some guidance if you are not purchasing your pins from Disney directly (which truly is the only 100% guarantee you are getting an authentic pin). Another good write up I read last year came from Ebay FAQ - its worth reading if you are going to venture into Disney Pins -

from dizpins website:
"After much research, one can assume that unless you purchase a pin directly from a Disney venue, the authenticity cannot be guaranteed. Any and all Disney pins have the potential of being a scrapper. It has also been determined that many older pins released over 4 years ago, are now appearing as scrappers. Noted below are some red flags to be attuned to when trying to ascertain if a pin may be a scrapper. Note that this list is not all inclusive:
-Most scrappers come in a plastic bag with one staple closing the bag.
-Many scrappers may have an error on the pin, whether it be on the coloring or on the backstamp. Some do not have any errors noted.
-Look for sellers that may have many of the same pin of a low edition size.
-Look at the location of the seller, if shopping on an auction site. There is a high probability that pins shipping from Asia are scrapper pins. Also read the description closely, and note why shipping costs to you may be high, i.e. pins being shipped from China.
-Look at pin lots. Ask what pins are being sold. Ask what is on the backstamp.
-If you are unsure of a pin, check it out on Pinpics, as many scrappers sold are pins that are not yet released or pins that have been pulled for release by Disney.
-LE numbered pins that do not have a number noted are most likely scrapper pins. For example, if the backstamp is ____/1000 with no number or a blank space before the "/", it is most likely a scrapper.
-Pins that are not of a Disney character, such as the Precious Moments pins, are scrapper pins. The error is the ©Disney on the back."
I'll say again - Disney Pin Trading is NOT a cheap hobby to undertake. While quite a few pin traders are children that doesn't mean it "should" be a cheap hobby. Folks who are serious about allowing their children to undertake this hobby must be informed and do their research.
What do you do if you happen to unknowingly obtain a scrapper later to find out its not authentic?? - From the ebay FAQ I referenced earlier:
"I Think I've Bought Scrapper Pins...What Do I Do?
If you've bought pins from a Scrapper seller, you have an ethical issue to deal with. Like Jiminy Cricket says "let your conscience be your guide..."
Obviously, you're dealing with illegal pins. Do you choose to help the Scrappers by trading counterfeits? Do you knowingly sell pins that you know to be fake? Scrapper pins hurt all of us. For me, one solution is to give the pins away to kids who aren't normally collectors...they'll enjoy them without polluting the market. And next time, you'll know to not buy pins from that Scrapper seller."
