CASINO MUNICIPAL MALO-les-BAINS

0.50NF and 50F -- 32 mm
Both are the same size and color, but from different times in history, and both have the same monogram on reverse.

Other than the 5000 plaque seen at ChipGuide, I had an oval 500 (54 x 32 mm) and a 1000 plaque (61 x 43 mm), but both were lost in a 2005 hurricane when a building of mine was destroyed... and all I have remaining of those two pieces are photocopies (no scans).
