I have been looking to buy some pins through Ebay. I see a lot of lots with mention of Sedesma Pins, but am really not sure about those. My father says he overheard someone in the know at Disneyland say not to get Sedesma pins because they are cheap Spanish pins that have less luster. How do they compare with the real Disney? And are they tradeable? I saw a realy old Dis thread when I googled Sedesma by someone who said she was unable to trade them. Thanks for any advise!
