Personally if I find a matching serial number and I can pick it up for a reasonable price I will take it but whether or not it is worth it to anyone else is a different story. Bottom line is if you like it, can afford it, and want it, buy it.
I would not want to overpay for something that I only bought to speculate with and then get stuck with it.
But this is only my opinion. I'm sure others here have theirs'
