On December 23, an unknown person withdrew 100 BTC (over $ 750 thousand) from the Casascius S2-BAR-100 bar, created on February 4, 2013.

In 2011, American inventor Mike Caldwell began minting coins and bars called Casascius, in denominations of 1, 10, 25, 100 and 1,000 BTC. But on November 27, 2013, the U.S. Financial Crimes Service banned him from selling pre-funded coins.

Casascius coins have always been in demand and often sold above the value of the bitcoins kept on them. For example, in April 2018, when bitcoin was about $ 8,000, someone sold four coins at 1 BTC for $ 10,000 each.

On July 1, 2019, a 1-BTC Casascius gold coin in perfect condition was sold on eBay for $ 99,000. A coin with a hologram error was sold at an auction in November 2017 for $ 50,000.

In November 2019, 27 coins with a total face value of 71 BTC were cashed.

Since Casascius bars and coins were issued in 2011-2013, they also contain an equal amount of Bitcoin Cash.
