2024 update:
20BTC: 88 (26 intact)
10BTC: 107 (27 intact)
5BTC: 144 (49 intact)
1BTC: 589 (297 intact)
Seems a lot of the 1BTC have been cleaned out.
Intact means the bitbill contains as much (or more) value as indicated on the card.
Thankyou for the update! I guess the higher Bitcoin goes the more people will peel....please keep on peeling...makes the loaded ones rarer
