19,676 Casascius Physical Bitcoins Left to Peel
During the last six months, approximately 244 Casascius physical bitcoins were redeemed for their digital value. The Casascius physical bitcoin collection created by Mike Caldwell is one of the most popular physical BTC collections. The rare coins are often sold for more than the digital face value and today, there are 19,676 physical coins left unredeemed or active, according to casasciustracker.com stats.

Each physical bitcoin has a different fraction of digital BTC, as some coins carry .5 in BTC value while some hold a single BTC. Caldwell also made gold bars with bitcoins loaded onto them like the popular 100 BTC gold bar. There are Casascius physical bitcoins that hold 25 BTC and even units that carry 500 to 1,000 BTC. For instance, on March 30, 2022, an "S1-COIN-25" that's worth 25 BTC was peeled and redeemed for the digital value of $1.14 million.

The S1-COIN-25 also held 25 bitcoin cash (BCH) and 25 bitcoinsv (BSV), but those crypto assets have not been spent by the Casascius physical bitcoin owner. Five days prior, an "S2-COIN-5" was peeled and redeemed for 5 BTC or $230K. That Casascius physical bitcoin owner also saved the 5 BCH and the 5 BSV, as it has not been spent. While there are 19,676 physical coins from the Casascius collection left active, 8,262 have been redeemed so far.
