ISO: OLD "pin"

[catwho]

The first time I visited WDW my parents let me have 2 souvenirs (provided they didn't cost more than $5 each {sigh}) Anyway, one of them I still have (a patch with my name on it) The other one has disappeared and my mom thinks she threw it out. It was a plastic pin of Pluto's head. It was maybe 1.5" x 1.5" I've searched ebay time and time again and just have never found anything. Everyone has the "new" metal pins. This was purchased in 1976. If anyone has one or knows where I can get one would you lmk? I'm just sort of sad that I lost half my souveniors.

TIA!
