Differences - 1989-92 Racing Champions 1:64 NASCAR

I often see other sellers misrepresenting early 1:64 scale Racing Champions NASCAR die cast. What this does is dilute the market with values that don't apply to the items people are purchasing.The difference in values can vary greatly from one year to the next on some drivers. For example, the 1989 Davey Allison has a low value of $70.00 while the 1990 issue's low value is $20.00. And a 1990 Sterling Marlin has a low value as high as $50.00 while the 1991 Marlin values as low as $5.00. Which would you rather have paid $10.00 for? These are the low end Beckett Values. High end values of a pristine card
