Changes in back stamps?
Hey guys,
I started off my collection properly today bar a pin I had from a few years ago. I was just wondering if there was any information on how the back stamp has changed over the years? I'm talking about the OPT logo mainly. My old pin is from 2006 and the new ones I have are from 2011 and they logo has changed quite a bit. I'm hoping they're all real pins although I'm fairly confident they are!
