You need a gram scale for coins, ounce scales are for food and postage. A scale accurate to +/-0.1 grams will cost less than $20. In the meantime, you can just use a simple balance beam for a qualitative measurement.

I buy small scales from a company called Awesome Wholesale. I don't think there is a minimum. I order from them time to time. They have scales for under 10 dollars. These are the same scales head-shops and dealers get 25-35 dollars each.

Bury them in the ground for a few years in acidic soil. The zinc cents will rot away while the copper cents should remain largely unaffected.

well the smallest scale I can find is in increments of one gram or .1 of an ounce.
I'm afraid that the copper penny will get rounded to 3 grams (it's 3.11)
zinc penny will also get rounded to 3 grams (it's 2.5)
copper penny will get rounded to .1 ounce (it's 0.0881849)
zinc penny will get rounded to .1 ounce (it's 0.109702)
I could be wrong about this but I don't know if a scale with increments of 1 gram or .1 of an ounce will help me and that's as small as I can find.

do you think that a scale that can weight as small as a tenth of an ounce will work that is small as I can find. I've checked all food stores and general stores and that's as small as I can find.

Alot of convenience stores have digital scales.
They keep them up front with the "tobacco" pipes and bob Marley t shirts.

get a diabetic food scale from any drug store, under $30 will get you .05 gram accuracy. for $50+ you get .01g
with canadian pennies you can tell by color, the zincs are more pink.

While not cheap, you can purchase a scale used for weighing gemstones. Below is my scale weighing a 1955s Lincoln Cent in both Grains and Grams.   |

I saw this thread and decided to try a tool I use for something completely different: http://www.hobbylinc.com/htm/pin/pinp4035.htmNOTE: I bought mine from Hobby Lobby. The link above is just to describe the item. It's available in most hobby stores that have Pinewood Derby items. That's a tool to check weight and balance on a Boy Scout Pinewood Derby car. When I saw this discussion, I pulled out my scale and weighed a 1946 wheat. It was 3.0 grams. Then I weighed a 2011 shield - 2.5 grams. The nice thing about this scale is that you can zero it out with something on it. So if you have a coin in a saflip and don't want to take it out, just zero the scale with an empty saflip first. There may be cheaper solutions, but here is one for about $20 that will definitely and digitally differentiate between 2.5 grams and 3.0 grams without fail and should be available from any hobby supply store that stocks materials for the Cub Scout/Boy Scout Pinewood Derby races.
