Can anyone tell me which of these pins in real and which is a knock off?

I've done a little online research and found a few clues to picking out fakes (aka scrappers), but haven't really found a good source that shows examples of each.

These 2 ended up in my daughters collection and I was just curious which was the real deal. I've seen both styles of backs on known legit pins.

To me the one on the left looks more legit, but..... Here is the link to pinpics version if you haven't already seen it. http://pinpics.com/cgi-bin/pin.cgi?pin=64386&sid=5147.1328052597.v2 There are a lot on ebay that have better pictures, do a search on toddler peter pan pin.

What are the dates on the backs?
