Sir, these are heirlooms and investments that offer her protection and you some fun from time to time.
Tell me...does a wad of cash protect her. You're doing this for her...(Example of the line I've used w/ my wife from time to time)
I have a best buddy (old Coast Guard friend and former Marine armorer) that keeps his entire savings in firearms. He has never lost a dime and in fact made some $$$. When he needs some cash, he never has a problem finding a buyer. He likes top end firearms for his investments... Colt revolvers, S&W revolvers, pre-whatever Winchesters and Sakos, Kliengunther rifles, etc. Kinda like Argonaut in his collection. (Off topic - I hope to attend Argonaut's memorial service in Weiser this Saturday... will depend on the weather and travel conditions.)
