When kids are let alone to pursue their interests amazing things can happen. My husband brought my son on one metal detecting outing with co-workers and he was hooked. This new interest is already combining reading, history and science. He talks about it non-stop, read an entire adult book on metal detecting from cover-to-cover and has done plenty of internet research on great finds.
I was so excited for him when he brought home this coin after his second outing. His next challenge was figuring out how to clean it. Coins are made out of a variety of different metals. Some cleaners and methods work well with certain types of coins, but can ruin others.
So he did some more research on cleaning coins.
First he tried a toothbrush, soap, water and hydrogen peroxide. The coin looked much better than when it came out of the ground.
Next he tried glue.
He covered the coin with glue and wrapped it in wax paper.
When the glue dried he opened it and peeled off the glue.
This process was repeated several times and the coin did look better.
Then he tried to freeze it with a little water. Some of the gunk was supposed to come off when the ice was knocked off. It also worked to improve the coin.
Some more experienced metal detectors took a look at the coin and said it probably wasn't very old and likely not a valuable coin. Maybe he will be luckier next time.
