Vintage AJC Roller Coaster Pin- 833 $25 or $20 w/offer

This vintage AJC roller coaster pin is ideal for the thrill seeker. It has non magnetic gold colored metal. The gold has never discolored but I doubt it is solid gold. But definitely not mixed metal. Perhaps gold over stainless steel? The pin is in very good condition. It was bent previously but I think I fixed it.
