I am need of a metaphor to understand the volume of prewar cards compared to post-war. Could someone break this down in simple terms? Obviously, there is some variation depending on how far back or how fast forward you go, but I am just interested in a "ballpark" estimate of each. Perhaps by the end of the thread it will be necessary to break it down more specifically per decade in each said era....So, for example, a simple "run of the mill" common T206 might sell for $20 and its equivalent 1950s common, $2. Therefore, the pre-war stuff is (generally) x10 more scarce?
