do you think in the future they might be worth $10-20,000 being consecutive & engraved,,,say .....put away for 20 years or so???
Wish I could see your pics (blocked site from here at work - I'll have to wait until tonight).
If you mean $10 - 20K for the pair, I would expect that they would easily fall in that range for the two of them by 2027 - assuming the firearms market doesn't change too drasticly in the meantime. For that matter $6K invested in a guaranteed certificate would be worth $20K by that time. I wouldn't advise buying investment grade guns, if you're weighing them against other forms of investments - the risks are generally higher than conventional forms of investments, but the potential returns aren't necessarily correspondingly higher. My personal approach to buying guns as investments is to buy pieces that are undervalued in today's market, IMO. The idea being that, if you bought them for less than they're worth today, you should be able to sell them for a profit in a matter of months or a couple of years. Even if you only make 20% on your initial outlay, if you get that kind of appreciation in 12 months or less, that's a pretty decent ROI.
The longer the term you have to hold the item for, the higher the risk and the harder it becomes to average even 5% over the whole term (over and above inflation).
I should also admit that I've been known to get attached to guns I initially bought to resell

. That can be an expensive proposition considering you don't generally take an unturned SAA and shoot it just because you decided not to part with it. You only have to look at the average collector's estate sale to see what ends up happening with those.
Taking all I've said here and distilling it down to its essence, I would say:
- if you see yourself buying these two Colts primarily as an investment, make sure you get them for at least 25% less than you consider current market value and take the necessary steps to try to sell them in the next year or two.
- if you really think you will keep them for 20 years, you might consider shooting them. Can't believe I said that but, how much does the average buyer really pay extra for an unturned one (or pair) over a well maintained identical pair?
