<p>2013 Casascius 1 Bitcoin. Loaded. Firstbits 1Ag7sqAU. Series 3. Silver. Proof-69 Deep Cameo (PCGS). Loaded with 1 BTC. Produced in a full ounce of .999 fine silver, this Series 3 Casascius 1 BTC is an astounding treasure. The surfaces are brilliant and virtually flawless, boasting intense luster and sharp reflectivity on both sides. Just 1,817 examples are known in silver for 2013 Series 3, compared to the 6,653 brass coins recorded for Series 2 the same year. However, over 12% of these silver Series 3 coins have since been peeled and redeemed, further increasing the rarity of loaded examples like the present specimen. These silver 1 BTC are rarely offered publicly, making this a monumental opportunity for the advance collector. While we have offered two examples of the "Gold Rim" 1 Bitcoin since the beginning of the year, this piece represents the first of the full silver finish weve handled during that time. A "Gold Rim" recently earned $78,000 in our June 2023 auction, and this seldom-offered piece could achieve even greater heights.<p>This issue represents the culmination of this denomination that began with the brass Series 1 in 2011. By 2013, the production quality and security features of these coins had been perfected, providing an ideal self-storage solution with a sophisticated and attractive finish. Unfortunately, production of the Casascius series was ended in 2013 and the opportunity for a Series 4 was never realized. Nearly a decade later, the silver Series 3 remains heavily prized by both crypto enthusiasts and traditional numismatic specialists.<p><p>The obverse features the Bitcoin currency symbol at the center with the date, denomination, composition and motto surrounding. The devices are boldly rendered with a rich satin luster, starkly contrasting the mirrored reflectivity in the fields. An entrancing binary code decorates the border on the reverse, set against mirrored fields. A golden holographic sticker sits at the center with the Firstbits address visible through a rectangular window. The edge of the hologram also features a "laser rimming" technique which was intended as an additional security feature.<p>Specialist Elias Ahonen reveals that "Casascius [Mike Caldwell] had originally intended to produce 5 BTC silver coins but, though the mold was created, the plan was scrapped in favor of 1 BTC, 0.5 BTC, and 0.1 BTC series 3 silver coins due to the tenfold rise in the bitcoin price over the [prior] four months to 140 USD."
