I did some rough calculations and beating on a cent to increase the diameter to roughly quarter size (Which is larger than the OP coin) would require the thickness to be reduced to about 75%. Noticeable but not real obvious. Since this one has not been increased in diameter that much the reduction in thickness would be even less. Nickel size results in a thickness of about 90% of normal. Since you really can't compare the thickness of even two unmolested cents, and we don't know what the rim thickness was of this cent before it was abused, having the thickness very close to that of a normal cent is not surprising.
Thank you. This is a forum to dispense numismatic information. At the moment there are about 14 posters on the NGC U.S. Coin forum and probably a hundred here. They should shut their site down. I believe all posters are welcome here and all questions are reasonable no matter the skill level of the questioner. LONG ANSWER: Now, I get a bad rap mostly by the long-time "EX-PERTS" here (many of whom do not seem to have any FORMAL numismatic training), because I don't suffer ANYONE (including myself) posting nonsense, miss-information, stuffy high-brow over-the-head technical stuff, posing mythical scenarios, and especially faking "knowledge" of things they know nothing about. Whew! Then, I attack ignorance in a fun way (for me) . I want proof of opinions. If it is not provided, I dig in more to get the record straight. Perfect example: Shortly after I joined, one well-regarded and esteemed member here made up a blatant lie about procedures at the Mint. That stuff is how "numismatic myths" develop. It serves no good for any of us but sure made the fool look important at the time. After that, some would "ignore him." Not me, I will not ignore anyone as we all have important things to write (sooner or much later). We are all ignorant about many things. You will not catch me BS or posting about things I do not have at least a minimal amount of experience and knowledge about. I feel that those who are also ignorant on a subject cannot stand it when someone is so sure about something and questions their beliefs or asks for proof! It's only natural. As I wrote before, I know a little about coins. I look very closely at them on a daily basis and read a lot. I speak with nationally-known, well-regarded professional dealers/TPGS employees on a monthly basis. I CONSTANTLY learn from them and the posters here. NEVERTHELESS, I consider myself only a little above average numismatist. I'll never reach the caliber of Bressett, Downey, Halperin, Terranova, Weinberg, and our very own curmudgeon Doug. SHORT ANSWER: Finally, I am a very caustic and sarcastic person. That is why I have a well-deserved bad rap.
I once asked what type of formal numismatic schooling was available and other than the ANA summer seminar I am unaware of any programs out there. Is there anything out there I should be made aware of?
Key to my answer is "formal." I believe there is at least one "formal school" besides the ANA but I'll confess to kissing it off w/o looking into it. SOMETHING I DISCURAGE (See above). I know ANS in NY holds classes or they did a while back mostly on classical numismatics. Just Google "Numismatic Education" or something similar to see what comes up. Otherwise, there are many choices for informal classes (no diploma ). Coin clubs, TPGS's, and professionals such as Michael Fazzari provide hands on seminars on grading/authentication. It boils down to doing some research.
No, I am not new to this. I've been in the hobby since the 1960's. I had not heard of this particular error/counterfeit. Thanks for your snide comment, however, it shows your colors pretty well.
