Longterm value in Vintage Cards
Obviously, prospecting tends to be the way people make money quickly...of course, there is also a fair amount of risk.
How about Vintage cards? I haven't been collecting long enough to notice longterm trends. How consistent (or inconsistent) are vintage card profits? Can you expect a fairly steady growth or decline (i.e. 5.0% gain / year)?
For example, taking the '56 Mantle, PSA 3 values rest at about 270-300. Go back 5 years, were the prices any different? How about 20 years?
It would be interesting to see a graph of various vintage card values, but I doubt anyone has one.
