2012 Casascius 1 Bitcoin. Loaded. Firstbits 1CSFguKQ. Series 2. Brass. MS-66 (PCGS).
Loaded with 1 BTC. A sensational Gem example with warm honey-gold coloration and strong luster. It ranks among the finest examples graded by PCGS and only two are listed higher. While the 2011 and 2013 Casascius 1 BTC appear with relative frequency, the 2012 1 BTC is very scarce on the market. According to researcher Elias Ahonen, only 4,089 2012 1 BTC were issued, which was less than half of the 8,352 that would be issued for the 2013 1 BTC. Over 30% of the 2012 1 BTC have since been peeled and redeemed, making this exceptional loaded example a true prize for collectors. Issued on a 28.5mm brass planchet, the obverse features the Bitcoin currency symbol at center surrounded by a legend listing the date, denomination, and the Latin phrase "VIRES IN NUMERIS" that translates as "Strength in Numbers." The reverse features a tamper-resistant holographic sticker with the firstbits address printed at the center. Beneath the holographic sticker is the private key that, once revealed, allows the owner to sign a transaction, thus "spending" the bitcoin attached to this coin.
