Hold on to your commonfoil hats, friends. We are opening a Collectors Box of M21. There’s quite a bit of value in some of these packs. There’s also a criminal amount of low value compared to the retail cost of an individual pack.
In my honest opinion, you should NEVER buy these collectors packs individually unless you really enjoy gambling. Exponentially moreso compared to a standard booster pack.
For my own sanity, I only priced the rares in the box. Prices shown are Market Value from TCG Player as of July 12, 2020.
