One of the people I learned a lot about collectibles from once told me "you can never pay too much, just too soon."
Of course, for some things depending on what price you paid and what it was it might be as mush as a few generations too soon.
I have a bunch of stuff I paid "too much" for, some stuff I overpaid for on the early 80's is much better than it was then. The stuff I bought new from the late 80's to early 90's............Maybe my kids will live to see it become worth what I paid, maybe not.
