*** Moved by Staff to a more appropriate forum. Previously posted in the Main Coin Forum. ***As indicated in the topic the coin Waze far less than it should and is much closer to if not exactly on the mark for a zinc coin. However, when dropped does not sound like zinc but more like a token or something that you would have had in the 80s at a Chucky Cheese or something. Any thoughts?

Any thoughts? What is the diameter and the thickness? (Maybe just take a pic of the edge with this cent sandwiched between two "normal ones".) Normally, low weight cents are either really worn or have suffered through an acid bath at one point. The front of this coin looks normal though. Please include an overall pic of the rev too. If it is struck very weakly, then perhaps this was struck on a thin planchet, although that seems unlikely given the reasonable strike on the obv. One more thing--can you confirm that your scale is measuring properly? "If you climb a good tree, you get a push."

I just opened it up out of a coin roll this evening and confirm that my scale was reading correctly by weighing a few different cinq cents of the late 90s some Shield sense and some 60s and 70s toppers. The scale was reading correctly and nothing seemed out of the ordinary when it comes to a bulge in a roll or anything like that. I'll try to put a scale on it this evening to confirm that it's the proper size. It's definitely like though. The only reason it stuck out to me was the way it sounded when it contacted some of the other coins when I was sifting through the role. It instantly stood out. I'm fixing to post a couple more pictures that have better clarity. I'll try and get some high-res images this evening post along with a side-by-side with another penny for scale.

  The coin was well-struck for the most part and seams normal other than the sound and the weight |

Here's a collage that I put together real quick showing the 77 versus the 1961-d laid out on a Brunton directional compass. As illustrated by the picture neither the 1977 or the 1961 move the needle on the compass, but 3 staples move the needle approximately 1 1/2 degrees or so Mas o Menos. You can also see some measurements of the coin on the calibration scale that came with my microscope. From the comparisons the 1977 is slightly thinner than the 1961-D, but the difference in weight vs the thickness lost doesn't make sense if they're both made out of the same material. It's clearly not ferrous given the fact that it didn't impact the compass so... Aluminum Maybe?  |

Ok thx for all of this new information. If it was made from aluminum then that would be a find indeed. I would sooner believe that your coin was struck on a slightly thin and underweight planchet. This would explain the broad area of weakness on the rev (although that could just be a whole bunch of grease in the die). Hopefully someone else here will weigh in too with their opinion.

I do see weakness on the bust and on the reverse side.
Errers and Varietys.

More food for thought. I was checking the US foreign coinage spreadsheet Mr. Potter shared with us and see one country listed with similar dimensions, weight and a copper / zinc composition. The only problems are the blanks are more brass in nature and has a scalloped design. So struck on a foreign blank seems unlikely. But blanks punched from foreign stock material, though unlikely maybe a possibility. Country: Philippines Year: 1977 Mint: Philadelphia Denomination: 5 Sentimos Composition: 60% copper, 40% zinc Weight: 2.5 grams (NGC lists 2.4 grams) Diameter: 19mm Note: Scalloped design  All that said the subject coins appearance seems that of a US cent composition. So blank punched from rolled thin stock is most likely. Thanks, Doug. |

How about images of the 7:00 edge on obverse (1:00 on reverse) of the coin. It appears weaker on that area from the images provided.

It definitely has a brighter and more brass-like sound quality over a standard zinc cent. I suppose losing thickness and perhaps a marginal to negligible amt of diameter could have that kind of dramatic impact on the weight. Basically I have 4/5's of a coin. Thanks Doug.
Coop what you're saying is true, but how does it tie in? It kind of sounds like you're suggesting an additional minting issue that goes beyond thin rolled stock, but maybe I misunderstand.
If not, is it worth keeping?....Or should I find a restaurant that still has one of those old school $0.01 gumball machines. :)

Struck on planchet punched from rolled thin stock.

is it worth keeping? Well, the purchase price is only one cent, so I'd probably keep it. I'm not sure that it is worth much over face value, but an interesting coin nonetheless. "If you climb a good tree, you get a push."
