But master,
I is not a collector.
I'm not trying to give anyone ideas but I'm of the belief that the creative thieves are just over the horizon. If the only thing standing between a 10,000.00 3" barrel revolver and a 1,500.00 3" barrel revolver is a serial number, how long before somebody invokes the tech to change a serial number?
It's not like the "good" serial numbers aren't published where everyone can see them or that Colt balks in the face of multiple letter requests for the same number... yet ...
A stay in club fed and the cost to tweak a serial number may not be worth 8,500.00 but it might be worth 18,500.00.
I see interesting times ahead regardless of due diligence.
It's a natural and inevitable part of pricing going too far beyond creatively rationalized intrinsic value. It has a history going back 10,000 years and probably won't respect the fact that most collectors are gentlemen. On the contrary, it will probably prey on the observation.
