2011 Casascius 1 Bitcoin (BTC). Loaded. Firstbits 18DaMtK8. Series 1. Double Error Variety. Brass. 28.5 mm. MS-66 (PCGS). This is an active and loaded cryptocurrency coin containing 1 BTC. However, the intrinsic crypto value does little to convey the significance of this incredible rarity. Outside of the unique prototype gold 1000 BTC coin, the 2011 Double Error is the rarest variety in the Casascius series and is considered to be a Holy Grail of the entire cryptocurrency category. Among the nearly 28,000 coins issued as part of the Casascius series, there are only five reported examples of this 2011 Double Error. Casascius creator Mike Caldwell confirmed this himself on his blog, posting a picture of a note that says "Only 5 out of my batch of 11,000 have the address printed above center."<p><p><p><p>It boasts the same misspelling of CASACIUS on the hologram as the "regular" Error variety, but also features the firstbits address printed 3 mm too high in a second error. Graded MS-66 by PCGS, this specimen exhibits nearly flawless surfaces and lovely golden-tan coloration throughout. It was loaded on November 6, 2011, making it among the earliest funded physical crypto coins of any type and further compounding the desirability.<p><p><p><p><p>While five may have been produced, not all five have been confirmed to survive. Specialist Elias Ahonen points out that "Considering that about a fifth of the series 1 1 BTC 2011 coins have been redeemed, it is probable that not all five remain unredeemed. Of any that have been redeemed, it is very unlikely that the peeled hologram(s) will ever surface as they were not considered worth preserving." Even if all five are eventually located, this population still falls dramatically short of collector demand as interest in this series grows at an exponential rate. <p><p><p>Traditional numismatists will recognize this mintage of five pieces as a match to the famous 1913 Liberty Head nickel, and dramatically fewer than the survivors of the Original 1804 dollar and 1894-S Barber dime. These multi-million dollar treasures have long been treasured by collectors for the roles they played in the history of the United States. In the evolution and development of cryptocurrency, this Double Error serves as a similarly significant milestone. <p><p>Public Address: 18DaMtK8BZAhvmkQznWCMXm6GNK2jszdyx PCGS# 906442.
