What is an Auction Pin?

A Disney Auction pin is a special type of limited‑edition Disney collectible pin that was originally sold through Disney Auctions, an online auction platform Disney operated in the early–mid 2000s. These pins are considered some of the highest‑quality, rarest, and most desirable pins in the hobby.

The end of DisneyAuctions.com (2007)
DisneyAuctions.com shut down around 2007, and the Auction pin program ended with it.
Afterward, Disney moved all online pin sales to:

DisneyShopping.com

later ShopDisney

No LE 100 Auction pins were produced after the shutdown.
