P.S. A hundredth of a Shekel is called "Agora", or in plural "Agorot" so those would be the proper equivalent of a cent.

Are you sure your piano isn't a Yamaha U3(?), as it looks much taller than a regular U1, but not quite as tall as a standard YamahaU5.  You can verify which model it is, simply by lifting the lid and peering at the gold-painted, cast iron frame at the upper right hand side of the frame; the model number is cast into the frame and the U plus 1, 3, or 5 are painted black.

Just my two shekels worth,

Joe

That's my old faithful 1965 Yamaha U1 damped with a home made felt sheet.
