This is what the three plaques looked like while they were in thier original state of preservation in the early-1990s http://community.webtv.net/BENEDICT/CASINOMUNICIPALdu
...and below is the only piece that survived a short-term, improper storage after Hurricane Wilma in 2005.

The other two pieces in the link turned into a glob of melted plastic.

They're the only three scans I have of the three denominations.
