2007 Bridge to Elbląg 10 Złotych

The 2007 10 złotych coin highlights the Bridge to Elbląg, part of Poland's Elbląg Canal where boats are winched over land on inclined planes—a 19th-century engineering oddity still in use.

That setup alone makes the coin's design noteworthy, with its obverse featuring the bridge's arches and the reverse showing a boat on rails, all struck in silver by the Warsaw Mint. Details like the exact alloy composition remain standard for Polish commemoratives, but specifics on the bridge's depiction draw from historical blueprints.

We don't know the precise mintage figures; records from that era can be spotty. What is clear is that this coin appeals to those fascinated by infrastructure, not just numismatics.

Engineers might appreciate the irony: a coin celebrating a bridge that bypasses water entirely.
