have a chance to buy some old printing plates and was wondering what I could expect in terms of alloy
seller says theyre lead underneath the copper coating.
i can see the edges are a little scuffed/dented, so I assume it' softer than zinc.

I'm wondering, why copper coat it if it is hard lead? zinc or lead will oxidize less than copper if it's to be used for print, no?
thanks in advance!
