There are, IMHO, two values to a gun: it's collector value and what it's worth to you. The only question you have to ask yourself is which value is more important to you.
Personally, I don't really care what its collector value is, I'm a shooter first and a collector a very distant second. I collect guns I like and that I can shoot without much care about their value.
I bought a sleeved hammergun and likely paid more than its collector value was worth. However, the gun was in very good condition, it is in my opinion a very elegent and attractive looking gun, it fits me quite well and I can shoot it pretty well too. It was worth it for me as far as I'm concerned. I'll own and shoot this gun for the rest of my life.
