The value of guns like anything else like vintage cars or stereo equipment, it varies over time as anything else does. My vintage stereo equipment collection is worth 5 to 7 times what my gun collection of over 40 guns is worth. If anybody on this forum is into vintage stereo equipment, they will know the value of my 2 Sansui 9090DB's and Pioneer SX-1060 and Akai GX 747 DB which is only one of over 30 RTR decks I own and my 150 10.5" reels or my 300 reels of Maxell tape. But in the end anything I own is only worth what the next person who buys it is willing to pay.
