Its a family affliction...my dad, in his late 80s, also owns a triple digit number of firearms. My son, once when he was 18, bragged that he was one gun away from having 50 (I think he is at 50 now, about to be 51 next week when I give him that model 66). Heck, even my daughter, currently at 19 years old, has several, and she hardly shoots.
Nothing too fancy in the family, no Parker doubles, Africa triples, or anything like that. Mostly common stuff, Remingtons, Winchesters, Colts, etc. A couple dozen custom engraved, gold inlayed, etc. Less than a dozen moderately priced collectables (moderate meaning less than $50k value). I have a $250k insurance rider just for the guns, and I'm sure it at least comes close to covering them all.
It was normal growing up, and I never gave it thought, until I started seeing that most families don't own dozens and dozens of guns, in multiple safes, in every closet, under every bed, etc. lol.
