Poll Question:
The ring test is a method for determining copper cents from zinc cents. When flipped or dropped, a copper coin will make an audible ringing sound, but a zinc-core cent will not. This phenomenon occurs because the natural frequencies of the metals are different, one inside the normal auditory range of the human ear and one outside it. As hearing ability deteriorates with age, the ear's ability to discern these frequencies also diminishes. The purpose of this poll is to help determine as what age the ring test becomes unreliable. Although results will vary from person to person, hopefully a trend will emerge from the poll results. Age blocks presented here were chosen arbitrarily.
Please leave a post if you have further elaboration on your answer.

I'll have to put this to the test.
I'm 43 and I know my hearing is already pretty bad.

| I have a hard time hearing them, but I can feel the weight difference. |

| I can both hear and feel the weight diference. - Over 50. I find it best to drop them on a glass table top to hear them. |

| My wife use to count money for a local department store and she could hear the ring of a silver coin as she poured them all out onto her desk. I bet she still can. |

I am not a huge penny sorter like many of you. Maybe do $500 pennies per year.
I use the ring test as much faster than looking at the dates or weighing the pennies.
You can almost always know the result before hearing the ring as you can kinda tell from the weight difference between a copper and a zinc before you flip em on a hard surface to listen for the ring.
If anyone out there wants to use the ring test, experiment a bit on different hard surfaces as there is a big difference in the results. On some surfaces you cannot even hear the copper ring difference compared to the zincers as just no discernable ring. On other surfaces, its VERY noticible and VERY easy to sort the coppers from the zincs. |

| The ears aren't gone yet.. I can still tell the difference with the ring test. Also when I sift my copper pennies I can hear if there is a Canadian in there. |
If your percentages are low.. just sort more. If your percentages are high.. just sort more.

| Yes, the canadians do stand out using the ring test as well and easy to seperate out. But the rings of the canadians vary alot more between one another, most I think do to the wider variance of the canadian penny compositions over the years. But, just from the rings, I think the canadians used some variance in compositions for some years that they never published. I actually took a look into the canadian compositions over the years because of the differences in rings I was hearing. Mostly explained them, but there were exceptions with no explanation, that I could find anyway, looking at published compositions. |
