How long have you been collecting? Since 2012 Olympics

How many pins do you own? 300

Our first visit to the Olympics was to see HB play basketball. I didn't collect Olympic pins before. We visited Cadburys to buy some chocolate and swapped a Games Maker pin for a Cadburys pin. I saw a lovely sparkly purple Cadburys London skyline pin, but no one would trade with me.

I didn't realise it, but my father spoke to one of the managers there about it. To my surprise a letter arrived addressed to me. When I opened it, the special pin dropped out. I don't know the managers name, but I would like to thank him for sending me the pin.
