Being an FFL, I am always amazed how serial numbers / first production runs & the such do for value especially the older the item gets. I saw some article on Fox news about some new found & rare 69 camaro or vette that was valued & expected to bring $1mm at auction. It happens all the time with collectable firearms.
I'm sure it will be sold for crazy $$$$, but in the long run will be winner even though it is no different than any other 1LE made for that year...collectors are like that & having #1 off the line may not seem much to some, but down the road I reckon there will be a profit to be made on the car if it stays in like new condition.
Having said all that, getting the 50 ZL1 meant a lot to me...not that I bought it because I thought it was going to be money maker with Barrett some day. Just sorta floats my boat with the gig I'm in & heck, you never know.
If it helps hold value, so be it.
