The quickest and most sudden devaluation of anything that I've seen was how the prices distributors were charging for common full capacity mags (AR15, Glock 9mm, etc) fell into the basement when the AWB ended in 2004.
Yeah the neckbeards were still sitting on tables of "well used" 30 round aluminum AR mags with $80 price stickers at the gun shows, but I was pretty shocked that online prices seemed to fall like a rock overnight.
