I found three 18" Zildjian Avedis cymbals at the local pawn shop for $80.00 a piece. There is no key holing or cracks in any of them and it doesnt look like they have been cleaned (good thing) but they are not filthy. There is no sign of any ink labels which leads me to believe they are pre 1980"s. One of the cymbals has a brass grommet to prevent key-holing. I did not get a chance to measure the stamp but it looks like the average Avedis Zildjian one.
My question is:
Do to all of the different weights of cymbals how can I tell if they are rides or crashes? It seems to me that a lite ride may be similar to a medium crash or something like that.
Should I be able to tell by striking them or should I weigh them in pounds and convert to grams to get an idea of what they are?
Any advise would be appreciated.
