Come to think of it.....maybe a Tom Murphy-aged and Les Paul-signed customshop R9 Gibson Les Paul from (I think) early 2004 could be a good investment option. These had brazilian boards and there can only be a certain number available. There could be examples of other brands as well.....
What one needs in an investment is that the item's value must outperform the inflation rate of your country on a yearly basis. So for example...a guitar bought in 1965 for R180 must now fetch R6200 to have earned an 8% return on a year-on-year basis
Re-think....clearly there's something very odd about these figures. In '65, R180 was a lot of money, it was a top-layer monthly salary, whereas R6200 is about an entry-level salary now (??). That shows that inflation here ran at least at a compounded 13% pa to equate to a monthly salary of R49,000. That means that your '65 guitar should now fetch at least R50000. Most good original Fender Strats, Martins- and Gibson models from '65 can compete with this. However your Harmony's , Hofners and most Gretsch models won't.
