We have previously done different series which focused on low populations. Many of these cards were non-holos or reverses which don’t have as many total cards submitted. They are still big chase cards but typically those categories will have less PSA 10’s than holos. We are doing one final series, this time limited to only 50 which will include the lowest population holos rangining from 2003 up until 2011. Every single cards is a PSA 10 English language holos. There are no reverses or non-holos included so every single card is much more premium. Everyone grades their holos and that’s why they typically have higher populations. When you combine  very popular card with a low population and extremely low gem rate, you get a huge chase card that many collectors never have the chance to get. Since the average populations vary by era, we have different thresholds for each of them. We would only consider a card extremely low population if it stands out and has a much lower population than the average holo from the same set. We have some of the best possible cards from several early eras including some of the rarest Neo cards and Expedition holos. These are basically the most difficult sets to complete. The current average value across all 50 boxes is about $13,000.
