I put coins on my Alexander tubas around fifteen years ago. I did it for cosmetics, but noticed a change in the speed of the valves. Jeff Funderburk told me that it would make sense to speed up the valves with a little more weight on the other side of the fulcrum at the springs. Sort of like a teeter-totter. Even out the weight on both sides and everything becomes easier. I've never wanted to take the coins off.
