Verifying if pin is an Artist Proof

[AnBry]

I purchased a Mickey limited edition pin from the 20 Year Pin Trading Anniversary event that was held back in November 2020 (approx date).  The pin was purchased directly from the online registered event. The pin that I was able to get was the item #19 Mickey Guest Inspired from the 2019 Disney FairyTail Auction lot winner.  The pin is a Limited Edition 500 with Mickey and his pin board saying "Wanna Pin Trade?' and contains 3 tiny interchangeable pins (Stitch, Ariel and Tigger) and has the emerald stone in the bottom right corner.  In researching, I believe this is an artist proof pin but no where on the back does it have AP on it.  It has the Limited Edition 500 but I truly think this is an AP pin and knowing that I purchased it directly from the event I know the pin is authentic.  I was hoping to sell the pin, as I think I am ready to part ways with it, but don't want to advertise it as an AP if it is not. I also don't want to devalue the pin. Would like some suggestions what to do.  I also purchased other pins from this same event that were limited release pins (mystery pins) but the words 'limited released' were not featured on them.  Not sure if any others may have attended this event back in 2020 that have insight.  Thanks

If it were an AP pin, it would definitely have the AP on the back of the pin.  It is very unlikely that you would receive a pin from the RSP process.  The AP would either be stamped or etched on the back.
