Today i went roll hunting and found this penny mixed in with a bunch of shield cents. Didn't see it until i checked one by one. Cleaned? Don't know. But it sure looks nice. Have to check my other rolls.
I thought of that, but as i go threw the rolls i keep finding pennies in almost the same condition. Really don't know. Any thoughts?
Really? Mostly wheat? You may have found someones dumped collection or coins thrown into circulation in support of the Great American Coin Hunt! Can you post pictures of them?
I have a feeling that may be the source of the coins. Will post all the pic's. Should i post them here or on the roll hunting forum?
I suspect the chem instructor threw away all of the plated cents the students left behind from their zinc plating exp see below. . I have a beaker of them I sent to the bank after putting a deep scratch in the coin so they would not show up here Jim https://www.sciencecompany.com/Turn-Copper-Pennies-Into-Silver-and-Gold-Pennies.aspx
After giving your post a long Q&A with some colleges of mine, we came to the conclusion that these coins must have been rolled in and sent to this bank from the continental U.S. To explain this i would like to know what grade chem teacher would do this experiment?
This experiment can either be done as my previous post's url given or as electroplating with a small 9v battery. It is a favorite of home schoolers are well and has been included in quite a few lab books/teacher guides for 7-8th grade levels, 9-12 , and to beginning chemistry in colleges, and the supplies are packaged by several science supplies companies for school orders. I would have no idea how common they really are, but the forum keeps seeing more and more pop up, so I expect many. The experiment itself became popular in the late 50s -early 60s during the Space race after sputnik. Jim
That's what I thought. My school years were spent in Yonkers N.Y. We did these experiments too. The problem here is that on the island there were no chemistry clases given to students unless you were in college. Still I'm compeled to agree with your answer. Thank you.
