Mark1959 Pillar of the Community 7234 Posts	Posted 04/04/2018 9:58 pm looks like the zinc rot dots are forming - so only copper plated and 2.48 is probably within tolerance Report this Post to the Staff
dostocalo14 New Member Philippines 18 Posts	Posted 04/04/2018 9:58 pm Is it posible also for both copper and zinc cents to have high pitch ring sound on drop test? Report this Post to the Staff
dostocalo14 New Member Philippines 18 Posts	Posted 04/04/2018 10:08 pm Thanks for the reply goodman..but still I'm confuse..I tried every zinc penny I have even the closest one with the rot like dot youve mentioned still this is the only cent that has exact ring sound like other copper penny.

scstrawn Pillar of the Community United States 536 Posts	Posted 04/04/2018 10:34 pm A ring test is not the most scientific method, too many variables to affect the sound. Based on the weight provided, and the picture, you've got a normal zinc-ky. Report this Post to the Staff
dostocalo14 New Member Philippines 18 Posts	Posted 04/04/2018 11:27 pm You maybe right but still its too thin to plate more copper to be sound like copper cent..I mean it looks worn out and it means the copper plate worns out too for the penny still sounds like copper one ring drop test sound..by the way I will upload a video on youtube and I hope it will help me more..thanks for the help guys..really appreciated.

FrankenCoin Valued Member United States 150 Posts	Posted 04/09/2018 07:03 am Specifications for Copper: Metal Composition: 95% Copper - 5% Tin and Zinc Diameter: 19 mm Mass / Weight: 3.11 grams Specifications for Zinc: Metal Composition: 97.5% Zinc - 2.5% Copper after 1982 Diameter: 19 mm Mass / Weight: 2.5 grams There were some mistakes made on Planchets and I believe it would be best to weigh it and if it weighs 3.2 grams instead of 2.7 it would be the wrong Planchet and may be valuable.
