Greenstang Posted June 22 Share Posted June 22 Welcome to the Forum I don’t se a DDO but I do see a linear plating bubble. What are you considering DDO? Sandon 1 Link to comment Share on other sites More sharing options...

EagleRJO Posted June 23 Share Posted June 23 (edited) I see a plating bubble also to the right of the "7" in the date. The only known doubled die cent for that year is a 1997 (P) DDO FS-101 with a clear doubled ear from various sites like NGC VarietyPlus, The Lincoln Cent Resource site, and Variety Vista. And that's a typical "1" in the date. Edited June 23 by EagleRJO Sandon 1 Link to comment Share on other sites More sharing options...

powermad5000 Posted June 23 Share Posted June 23 Lincoln cents of this time period were a zinc planchet that was copper plated. There were many issues with the copper plating up till about 2005 or so. Some of the issues were plating bubbles, plating cracks, discolorations, easily damaged by the environment, and even sections of the plating falling off. I agree there is a linear plating bubble to the right of the date. A DDO is created when the die being made is struck twice by the master hub producing two distinct images across the entire surface. One of the more famous in the Lincoln Memorial Cents is the 1972 DDO. The following photo shows what a true DDO looks like and is from the NGC VarietyPlus page.

Louie499 Posted June 23 Author Share Posted June 23 Lol thank yall . I stopped collecting errors about 20 years ago and looking at the updated error lists , i have to go back threw ALL them again . Are there any shielded penny errors ? Link to comment Share on other sites More sharing options...
powermad5000 Posted June 23 Share Posted June 23 (edited) I have seen only a handful of legitimate errors on the Lincoln Shield Cents. Some retained die breaks and some struck thru errors. Please be careful when looking for these as eBay is loaded with hundreds of supposed "errors" which are merely self proclaimed and are not actually mint errors. And the sellers of these want majestic prices for said such non errors. Comparatively speaking of the billions of these cents minted over the nearly last ten years, there are VERY FEW actual errors to be found. Sulivan Numismatics has only a handful in their inventory. There are really not many true errors of this series. I just got one of mine back from NGC that I submitted as an error because on the reverse, S OF A in UNITED STATES OF AMERICA was basically nearly unreadable and I thought it would get an error designation for being struck through grease, but it came back straight graded.

Louie499 Posted June 23 Author Share Posted June 23 Ouch . That sucks . I just hit my digital microscope in yesterday . It is amazing . Last time i collected coins i only had a loope . This is a game changer . Now have to go threw over 6000 pennies again . I know it was over 6000 cause they weighed over 40 pounds Link to comment Share on other sites More sharing options...

Sandon Posted June 23 Share Posted June 23 On 6/22/2023 at 8:24 PM, Louie499 said: Is there a updated list of penny errors on the net ? Welcome to the NGC chat board. In addition to the sites previously mentioned, doubleddie.com lists doubled dies and other die varieties by date and mint, and error-ref.com describes various types of error coins. Doubled dies are usually classified as die varieties rather than as mint errors. See Variety vs. Mint Error | NGC (ngccoin.com) Please note that the mint has been using a "single squeeze" die making process for several decades now, which has essentially eliminated the production of significant doubled dies. Additionally, it is extremely unusual to find significant mint errors or die varieties of any sort in circulation, and the minor anomalies that are more commonly found, such as plating bubbles on copper plated zinc cents, have little or no market value and are usually not designated by grading services.

Louie499 Posted June 25 Author Share Posted June 25 How does a platting buuble happen ? Link to comment Share on other sites More sharing options...
powermad5000 Posted June 25 Share Posted June 25 I am no metallurgist, but I would say it is a dissimilar metal reaction between the zinc core and the copper plating. I do know from experience in the electrical field that we have to take special measures when splicing aluminum wire to copper wire as there is a dissimilar metal reaction between aluminum and copper that literally corrodes the splice if we do not use special dielectric coatings between the two metals when making the splice. Not all cents develop these plating bubbles so I cannot say for sure exactly what actually causes it. Link to comment Share on other sites More sharing options...
Sandon Posted June 25 Share Posted June 25 On 6/25/2023 at 1:21 AM, Louie499 said: How does a platting bubble happen ? Since 95% copper alloy ceased to be used in 1982, cents have been made from solid zinc blanks that have been electroplated with copper. If the electroplating process isn't done correctly, there can be a poor bond in some areas between the zinc and the copper plating, which turns into a raised "bubble" or, more correctly it seems, blister when the coin is struck. This occurred to many cents dated from 1982 until the mid-1990s, some of which appear to be covered with bumps and blisters. The electroplating process has improved since then, but it still happens from time to time, more often in one area as on your 1997-D cent. I've taken this explanation from a post by @Coinbuf on the following topic, which includes a link to an article in Coin World: powermad5000 and Coinbuf 2 Link to comment Share on other sites More sharing options...

Even though they are likely interchangeable perhaps a "plating blister" could be a "plating bubble" that has burst. Link to comment Share on other sites More sharing options...

What do YOU remember from grade school science (the type before climate fear porn and gender ridiculousness)? I remember that copper and zinc in the presence of an acid creates a "battery" in which one electrode is slowly eaten away and the other corrodes. Also, little bubbles happen. VOILA! Gas bubbles in your post-1982 cents. Link to comment Share on other sites More sharing options...
