Recently, a collector decided to open two physical Casascius bitcoin bars, each containing 100 BTC, with a total value of approximately $19.2 million.
Entrepreneur Mike Caldwell created the Casascius line, issuing not only coins of various denominations but also hefty bars calibrated at 100 BTC, 500 BTC, and 1000 BTC. For example, in Series 1 (S1), Caldwell issued 57 bars of 100 BTC, and only seven of them remain untouched.
The 200 BTC spent in 2012 were used by blockchain analysis platforms such as btcparser.com.
Of the pairs opened last month, the bitcoins were transferred elsewhere. Both contained 100 BTC and were part of Series 2 (S2). Caldwell made about 81 such bars, and according to casasciustracker.com, 30 of them are still undisclosed.
About thirty bars of 100 BTC were not spent.
Prior to this, the last expenses of 100 BTC bars occurred in October 2024, while an earlier episode took place in October 2021.
The valuable bars with a denomination of 1000 BTC have an even more complicated history: only 16 were issued, and only two remain sealed or unspent.
