To buy or not to buy? Colt sp1 1968

My wife likes to laugh at me anytime I tell her I am going to add a new piece to my collection because it is a good investment. She tells me that none of my collection is a good investment because I never plan on selling them, but I think she has just as much fun with them as I do.

It was $2500. Looking at 50 bmg now. Not sure how many digits The serial was.

Thanks, I'm try to get a feel on how I should price mine.
