The Rocky Mountain Philatelic Library holds two or three auctions every year. Bids are accepted by mail, over the internet or in person during the live auction. The auction catalogs are included with the bi-monthly Scribblings journal mailing and they are available on-line at the Rocky Mountain Philatelic Library Auctions website. The auctions feature single stamps, country collections, accumulations of postal history, covers and stationery that were donated by members and other individuals. The auctions are a main source of revenue used to support the day to day operations of the non-profit Library.
