Hi, I recently found a 1993 one cent canadian coin that only weighs 1.27 grams. It is very thin and very lightly struck (also dirty from circulation) I've attached a couple of photos, albeit not great photos from my iPhone for your comments and thoughts...... Thanks, Bill  |

Because they have errors in them so uploading the same ones over and over will never work.

Looks to me like the coin has been dipped in acid; the thin lettering is a good giveaway. Acid aside, the RCM didnt mint any coins for foreign countries in 1993 that were 1.27 g |

I never thought of acid.....would acid take away half the coin's weight and still be able to make out the engraving of the coin.....?

Sure would.
Type in 'acid coin' or 'acid penny/cent' in the search box for this specific forum and you'll see other examples

It has to due to the metal changing density when struck. The grains are pressed closer together creating less surface area to be exposed to the acid. That's why Nic-a-date works so well on dateless Buffalo nickels in the USA. |
