Do you weigh each one or weigh them in bulk? Ive been hoarding my 1982s separately but havent verified any of them yet

I found weighing the 82s one at a time with our shipping scale at work will do the seperation job, but honest, for me its much faster to drop them one at a time on a hard surface and listen to the sound they make when they hit. The coppers make a tinkling sound while the zincs make a thud sound. I can go thru them and seperate the 82 coppers from the zincs MUCH quicker this way.
In my neck of the woods, Copper 82's are around 35-40% of the total 1982's pulled from a $25 box. 82's are heavily zinc in my area. I weight each one on a gram scale after each box is sorted.
Albany NY region 60% CU 40% ZN but varies with batch. I do CWR mostly.
I've been watching 1982s lately because I lost a craigslist sale because my copper had 1982s mixed in. I'm putting together some non-1982 CU boxes in case this happens again. Slow going, best to seperate metals 1st then visually inspect for 1982. But sometimes sort all 1982s 1st when too much vibration present to use scale - like on treadmill or running trails or while interstate driving.
WEIGH EM...you can get a small scale off of feebay for less than 20 bucks and have it in less than a week. I use the scale to weigh rolls to check to see if it is worth my time to unwrap the roll...126 grams equals zero copper pennies.
in Houston the ratio is good mostly copper 82's about 80%.
I set my 82's aside, and then weigh them 10 at a time on my 0.01 G scale once I accumulate about 1000. I've sorted out 3090 82 cents thus far --- 2712 (87.8%) have been CU. I'm in Missouri.
