In Krause's Standard Catalog of World Coins I found the attached image of a coin of the Cook Islands depicting the Rialto Bridge in Venice, Italy (KM#695, 10 dollars 2009, with gilt pop-up). Other coins in this series show other famous monuments as gilt pop-ups.

I wonder whether E-Sylum readers can help me understand the pop-up mechanism.

Probably the coin is composed of two matching pieces of metal, a silver round and a gilt bridge, and the miniature bridge can be taken out of the silver round and placed upright. Is there a slot embedded in the silver round under the bridge into which the bridge has to be inserted to have it stand upright? Or is there a hinge that connects the bridge to the coin?

Many thanks for any information readers can give!
