This is a interesting error and I would like to share. This penny has a heavy die clash on the obverse which shows the columns from the Lincoln Memorial . There is a similar coin mentioned on Couch Collectibles . "HOW MUCH ARE 1983 PENNIES WORTH? VALUABLE MINT ERROR COINS TO LOOK FOR! These are rare pennies and other coins that sold at auction for some good money." Time Stamp 4:00
On the 1983/84 cents there dies went through a lot of die clashes those years. Don't open the full images from this link on a cell phone. It will take too long and you will not be able to see the images as clear on a phone. https://www.PCGS.com/cert/39644403 Seem to me way over graded because of the extreme die polishing of the dies? https://www.PCGS.com/cert/38343341 But when you see this happening a lot on graded coins, you know that this was a problem those years.
