That copper will be pricey


How about just the copper coating ?

Get some ferric chloride
It used to be available from radio shack

dissolve some scrap copper in it.


Dip the steel into that solution and it will plate it.

All the look, little of the cost of copper.


Silver solder would work




The tops of those chess pieces are rifle cartridges, looks like steel so probably cheap Russian surplus 7.62 39
Easy to get from a range since it's not brass - you can get it for nothing.


I'd just put them in a lathe and drill them from the bottom, screw them into the block, loctite for a permanent bond if you want to .



You could also reverse the colour schema, brass cartridges of different sizes /calibers for each type of piece on steel bases.
 
7.62-39 or 7.62-54?
They look almost as tall as a 30-06.
Hard to judge height in photo?
VERY NICE WORK though!
I don't know

All the 7.62×54mm I've seen is rimmed and those chess pieces are semi rimmed / rimless


It could be all brass 30-06 and the silver colour can be had using a "tinning" plating solution - also from radio shack for circuit boards.
