I also have an … unusual… number of OneDrop Deep States. Let’s see what they weigh. This time for additional spiciness 
I will dissasemble them, remove the side effects + bearing, and weigh each half independently.

monkeyfinger ano 2
23.24g, 23.28g

saturday market
23.11g, 23.13g
splash
23.14g, 23.10g
acid wash
23.19g, 23.15g
copper (new in box)
23.97g, 24.04g
nickel half-swap (with patina)
23.75g
copper half-swap (with patina)
24.35g
It does look like copper coating (and probably nickel too) adds about a gram per half, so maybe ~1.5g heavier in total?
I should have some solids to test in a bit, I’m doubting they’ll be any different than the splash or acid wash results.
