Serial #'s and Collector's Score
The influx on the current market of all the common and other moments have driven the collective market price down over the past months. With many common cards still being circulated at 40K+ now, there should be notoriety for those cards with a lower serial #. (Ex. Kyrie Irving #151 is going for around $30). Adding a feature to Collector's Score that would give you bonus points on that card being at a certain serial value. This would drive the price up on the lower serial value's leading to multiple outcomes.
1. Incentive to keep and not sell those cards for value.
2. Higher incentive to buy those cards to increase Collector's Score.
3. More profit for the future market.
4. Increase in general hype.
