Sorry for the crummy title, but its the best I can describe it.

When I turn on my cold water all the way a muted <thunk> sounds in the
faucet and the fixture jumps a little bit. If I turn it on slowly it
doesn't happen but if I have it turned on a little then crank it up fast it
still does it. So I presume it's related to how fast I drop the pressure.

Is what I'm hearing water hammer? Is it related to the condition of my 50
year old galvanized supply pipes. More importantly, will it harm my
washerless faucets?

Assuming I actually get around to changing out my pipes will this problem go
away.

Well after reading a bit about it, it doesn't sound like water hammer at
all, but still what would be causing the faucets to jump and move upon
opening? Could there really be that much air in my water supply?

Actually it does sound like water hammer to me, but it may be other.

City or well water? Do you have a pressure reducing valve, a expansion
tank?

Its just plain old city water. I don't have any reducing valves or
expansion tanks, really just a plain jane cold water supply system.

I suspect it might be related to the conditions of the pipes, in which case
it will have to wait a bit for that to be fixed. I was really more
concerned about it damaging the fixtures.

Actually those are THUGS in your water pipes. They are fighting a
gang war and trying to steal turf inside your pipes. They are a very
violent gang and they are all heavy drug addicts. They also blast
loud rap music on their boomboxers. With all this noise going on
inside those pipes, it's obviously going to escape when you open a
spigot, and worse yet the fighting intensifies whenever water flows
because these gangsters are often pushed by the water into enemy
territory, thus causing more fighting and shootings. As a result you
end up hearing the results of all this violence.

I highly recommend you install a gangster softener in your plumbing
system. Not only will the noise cease, but you will find yourself
ingesting less narcotics, since these drugs are often released into
your water when a drug dealer is murdered inside your pipes during a
turf takeover, or during periods of rioting or looting, which often
occurs after heavy water usage due to flooding in the city. This is
very similar to the Katrina hurricane in New Orleans, but on a smaller
scale.
