In Colorado, we have one gun show that everyone is proud of - the annual Colorado Gun Collectors' Club show in Greeley, now in its 58th year. Most of the sellers are old, so they have stuff to sell. There is a long tradition of individual private sale tables there, although the age of most members does not give this a long future.
Only Curio-Relics and Antiques are allowed in the door at the CGCA Show. No modern guns. No black guns. 800 tables of just collectible guns and gun-related stuff. The club awards thousands of dollars in prizes for the best display tables so there's always museum-quality stuff to gaze upon and real experts around to learn from.
No clothes or food or tools or coins are allowed. Or art or jewelry, unless it's related to American history or by native Americans. Colorado's background check and waiting period laws do not apply to Colorado residents buying C&Rs and antiques. It's the only gun show worth attending in this state all year. The other Colorado shows are shameless flea-markets.
Hotels are cheap in Greeley and the local politics are pro-gun. The lighting in the show hall is really good and parking is free.
Many of the big internet gun auction companies like Rock Island Auctions rent tables to meet the public and promote their services.
May 18 and 19, 2024 with two days of set-up on the 16th and 17th when the table holders have an internal pre-show for each other, before the public arrives. (For a premium admission price, members of the public can access the show during set-up, also.)
