SO i came across this 1982 D penny that weighs 3.00 grams its porb lost some of it weigh due to wear and on the date i see doubling But Im thinking its actually machine doubling... but i vould be wrong lol thoughts ?
It's copper, given the weight, and correct on the MD. We can especially see this between the date and mintmark. This MD specimen is even a more typical specimen for MD. Note that the outer devices are most affected by the wobble in the equipment.
Just bear in mind that when they are that shallow it is pretty much a cinch it is strike-caused. You are looking for two impressions that are just a tad ajar and of pretty near equal height, a lot of people do not think of that.
Congrats!!! Learning is occurring!! Always nice to see someone put in some effort, makes me want to keep helping. Do you mind a little pop quiz? Can you tell is its a large or small date?
Correct. Another tell to keep in mind about MD…until around 1990, the mint mark was added to the die afterwards, and since, on your coin, both the date and mint mark show the same shift: it is strike doubling (MD) and can’t be die doubling. The die was created before the mint mark was added. Beginning around 1990 the mint mark was added to the working hub die before the creation of the working obverse die. This change to the die making procedure was labeled the “single squeeze” method, and since that change, classic, old-style doubled die varieties became impossible. Go to Lincolncentresource.com to research the different classes of die doubling… As always, I am open to be corrected if any info above is not accurate… …imo…Spark
After refreshing my knowledge at Wexler/How dies are made,I want to issue a correction: For Business Strike coinage… In 1990 and 1991 the mint mark was added to the Master Die (not the working hub) and eventually was placed on the Master Design. By 1999, all denominations had dies created by the single-squeeze production method. Please refer to John Wexler’s article for exact timelines and verbiage. @Kevin Mader @charley @Danny Bulric @Collecting Nut @green18 @cwart @eddiespin I pride myself to offering accurate information on my posts and take full responsibility for any mistakes I make. I should have refreshed my knowledge before posting…imo…Spark
Mint marks were punched into working dies by hand up until 1990. In the mid-1980s, Mint officials changed the procedure for placing the Mint mark on all Proof and commemorative coins. In 1990, the procedure changed for the circulating cent and 5-cent coin. In 1991, the changes were implemented for the circulating dime, quarter dollar and half dollar.
