1983 ddo ddr penny weighs 2.90 grams and varieties help

[heanvimean]

Hi All,
I have a 1983 which weighs 2.90 grams and found it looks like I am having double dies obverse and reverse. One is that is it copper? Two is that it is actually DDO/DDR? Included are my best photos and please give advice. I thank you for the comments.

I'm not seeing any thickness or notching for a DDO or DDR.

As far as the weight goes all I can suggest is to calibrate your scale to make sure it is reading correctly. After that, you may need to have an XRF test done on it to determine the metal composition to see if it's struck on an off metal planchet.

Okay thanks for the advice. I’ll use the new scale to weigh it once more or so.

I totally agree with PP, there isn't any additional thickness.

In the modern coin era, it is extremely unlikely that you are going to find a doubled die on the obverse and the reverse on the same coin. You'd probably have better luck at hitting a huge lottery.

EDIT: I will add one more idea. Take a known good copper cent, a circulated coin. find a tile floor or a marble countertop and drop that coin about six inches from the surface. the sound you are trying to listen for should almost present a slight ringing sound. A zinc cent will not have that ring. Another thing is examine the coin very well. Look for any area where the coin may be showing a break through the top layer of the coin. Early zinc cents were prone to having too strong of a strike which caused the coins to rupture the copper layer and expose the zinc inner layer.

As far as the weight, it's closer to the weight of a copper cent than it is a zinc cent. It could very well have been struck on an underweight planchet, or as PP has suggested, the scale might need a slight calibration or new batteries or whatever. Scales when they are first turned on try to set the TARE (zero-ize) so make sure it it set on a steady firm area and then once that is done, place the coin onto it.

Scales that show to the hundredths decimal (X.XX) in grams is the best, it would not round up or round down the actual coin weight.

I have an article in my signature block that might help identify machine doubling as well as doubled dies. The article does show how E PLURIBUS UNUM should look like doubled, so a visit there may be beneficial.

Lastly, a website called http://varietyvista.com can show you a wealth of information on most of the modern day varieties - mainly doubled dies and re-punched mint marks.

Hello. I also have a 1983 Lincoln penny weighing 2.9 grams which I believe to be made of copper. I will upload an image shortly.

It is best that you start your own post as not to confuse the community on who owns the original thread here.

Hello everybody, thought I’d post some coins I believe to be errors of one type or another. I appreciate any and all feed back whatsoever.

It will be very hard for you to get someone to go thru all of these coins with you that have posted in someone else’s post. If you read above Gary mentioned it to you..for future help remember, these people volunteer their time, post new post for your items and only one coin at a time per post with pics of obverse, reverse, and the error or errors…I am sure it will be better and quicker for you going forward…GL

Hey, I goofed up again and apologize to anyone I may have annoyed ! I’ll soon get things done in a normal fashion hopefully! Thank you for letting me know k.

Quick suggestion for you guys that think your pennies might be copper at 2.9 g. drop it drop it next to a 2000 penny drop it on a wooden table drop it on any kind of table and you're going to tell instantly what if it's copper or if it's zinc. The sound is clearly different. You should definitely get a pre-1982 penny and drop it so you'll know exactly where the copper Penny sounds like as well.
