On December 23, 2019, an anonymous user redeemed a 100 BTC Casascius physical Bitcoin bar, valued at over $723,000 based on the prevailing market price of Bitcoin at the time. The bar, identified as S2-BAR-100, was created on February 4, 2013, by Mike Caldwell, the creator of the infamous Casascius physical Bitcoin collection. This redemption marks one of the largest single peels (redemptions) in the history of the series.
The Casascius Legacy: From 1 BTC to 1,000 BTC
Casascius coins and bars were launched in 2011 by Mike Caldwell, who embedded private keys under tamper-evident holograms on metal discs. The series included denominations of 1, 10, 25, 100, and 1,000 BTC, each backed by real Bitcoin on the blockchain. Production was forced to halt in November 2013 due to regulatory pressure from the U.S. Financial Crimes Enforcement Network (FinCEN). Despite this, the existing pieces have become highly sought-after collectibles, often trading at significant premiums above their BTC face value.
For instance, in April 2018, a 2011-vintage 1 BTC Casascius coin was sold for $10,000 on the Shire Society forum (when 1 BTC was worth around $8,000). In July 2019, a mint-condition MS65 gold Casascius coin (1 BTC) fetched $99,000 on eBay. The recently redeemed 100 BTC bar, with its intrinsic Bitcoin value alone exceeding $720,000, could have commanded an even higher numismatic premium if sold as a collectible.
Redemption Spree: A Wave of Peels
According to data from Casascius Tracker (casasciustracker.com), November and December 2019 witnessed a notable spike in redemptions. On December 22, a 25 BTC Casascius coin (S2-COIN-25) was peeled. Throughout November, a total of 27 Casascius coins were redeemed, accounting for approximately 71 BTC. Of these, 11 came from the 2013 series, with the remainder from 2011 and 2012. The Twitter bot @Casasciusbot has been actively tracking each peel event, sparking debate over whether holders are cashing out for liquidity or simply moving funds.
As of December 25, 2019, a total of 46,329 BTC remained locked in unredeemed Casascius products, while cumulative redemptions had reached 44,940 BTC. Each peel reduces the supply of intact physical coins, making the remaining hologram-sealed pieces increasingly rare.
Why Now? Speculations and Market Context
The decision to redeem a 100 BTC bar may be driven by Bitcoin's price action during 2019—ranging between $7,000 and $13,000—making $723,000 a substantial liquidity event for an individual. Meanwhile, some collectors argue that the historical and numismatic value of Casascius bars will only appreciate over time, potentially surpassing the value of the embedded Bitcoin. The 100 BTC bar from 2013 is one of only a handful ever produced, adding to its rarity.
Regardless of the motive, the redemption of such a large Casascius bar highlights the ongoing tension between viewing these pieces as financial instruments versus historical artifacts. As physical Bitcoin currency becomes increasingly scarce, the Casascius collection remains a tangible link to the early days of cryptocurrency.
