What is the difference between unlimited vs. limited edition series?

Unlimited Series
Many series released on NeonMob are unlimited, which means they will never sell out and there is no limit on how many cards are produced for collectors. However, each unlimited edition series is only available to collect for a specific amount of time; once the time frame for collection has passed, the series will go out-of-print for collectors. Because unlimited series never sell out, they can be re-opened for collection at a later date.

Limited Edition Series
Some series released on NeonMob are limited edition collections, meaning that each card in a limited edition series has a finite number of copies created for distribution. Once all the packs in a limited edition series have been opened by collectors, the series is sold out forever and will go out-of-print for collection. Because limited edition series have a finite number of cards available, many collectors consider these cards to be more valuable than unlimited series. Limited edition series cannot be re-opened for collection as no additional cards will be produced. 

With both unlimited and limited edition series, once a series is out-of-print the only way to collect cards is to trade with existing owners.
