A few years back I watched a 1959 Gibson Les Paul guitar hammer north of $200K at an auction. It had the bridge replaced, had been re-fretted and was pretty well warn. The buyer was in Japan and the guitar was boxed (I assume, heavily insured) and shipped oversees.
I was dumbstruck at what I had witnessed. However, they aren't making '59 Les Pauls anymore and the price is what the market will bear.
The prices have come down a bit since, but I assume it will be a good investment in the long run. I'm told the buyer is a player and collector and based on condition, he can play it everyday without fear of lessening it's value (barring anything unforeseen).
In the case of this M 17-3 K22, it was bought for market price. It will most likely be a solid long term investment. It is staying in the US. Sadly however, I don't think it will be used everyday like the Gibson I referenced above. I'm sure the owner will get a great deal of enjoyment out of it just the same.
I say "cheers and enjoy"!
Fondly,
your long lost nephew koz.
