Extremely Rare 2011 Casascius Double Error Full Bitcoin

Casascius brass "Double Error" Loaded (Unredeemed) 1 Bitcoin (BTC) 2011 MS66 NGC, Ahonen-pg 89. Total Issued: 5. Series 1. Type PF. 28.5mm. Firstbits 19guzSV7. Loaded in 2011. The first 'error' refers to the well-known misspelling on the hologram, where "CASACIUS" appears incorrectly-an issue that was corrected in later releases. More notably, the second 'error' involves the unusual placement of the firstbits, printed approximately 3mm higher than standard, rather than centered within the hologram. This exceptionally rare and desirable variety is certain to attract strong bidding interest from connoisseurs of physical cryptocurrency.
