1 Pound - Elizabeth II Menai Bridge, Silver Piedfort

Piedforts — struck at double the standard thickness on the same dies — have been a Royal Mint collector vehicle since their modern revival in 1982, used consistently to mark the annual pound coin reverse rotation. The Menai Bridge reverse was part of that rotating series honoring bridges of the four UK nations, with the Menai design representing Wales in 2005. Thomas Telford's suspension bridge, completed in 1826, was an engineering landmark that finally connected the Anglesey mainland crossing without tidal dependency.

Mintage for piedfort issues in this period was typically held well below 10,000, making most of them genuinely scarce rather than artificially so.
