Identification notes
Darabanth auction 385 lot 31216 identifies the 2012 MJB Monetary Metals copper round. Its supplied photographs show MJB 2012 and AOCS APPROVED on the circuit-board reverse, and 1 AV OZ .999 FINE COPPER on the Bitcoin side. AV OZ denotes an avoirdupois ounce; it is not a troy ounce. The auction lists 39 mm diameter. These are inscription and auction specifications, not independent measurements; issue-wide mintage is not established.
About the photographs
Both sides of the 2012 MJB Monetary Metals copper round, supplied by Darabanth Kft. The auction house supplied unwatermarked website-resolution copies because its old originals were no longer available. These illustrate the issue, not the condition or authenticity of an individual vault specimen.
