Two updates:
   One of the cards was sold for 50,000 sats, it had signatures from PlebRap.
   A new thing is happening, if you provide proof of destroying a Seed or Chris card, you get 9,000 sats each time.

There aren’t many of these cards in total, 21 designs, each limited to 210 copies.

Also, someone is now offering 100,000 sats for the PlebRap card #21/210
