You are working at it backwards. The first thing to look for is identical doubling, THEN bother looking for markers. There are a BUNCH of 1983 cents missing reverse design details. This alone does not make it a doubled die.
The missing E has to do with strike. It is not a die characteristic. This means the previous or next coin minted with the same die as your coin could have minted a completely normal coin...depending on the pressure of the press at that exact moment.
As for the odd coin - it's fine to post whatever you want. Nobody died and made me board boss, it is not my perrogative to gauge who does and does not post here, nor to gauge what they post. Thing is, when the same people post the same type of "odd coins" over and over again and are told over and over again what they have, it stands to reason that either they are going to learn and move on, or they're not going to learn. All it takes sometimes is one real decent error coin or one decent doubled die for everything to click into place, but you may never find either of those in pocket change.
Furthermore, the battle over the past couple of days has been authors and experts in the field stating that worthless is worthless, and the counter arguement has been that people saw some dealer selling them for a couple of dollars, or that they saw one sell on
ebay that looked just like this one, so saying they have no value is wrong. Fact of the matter is that they do sell...to people who believe the hype stories in the lot descriptions or to people who happen to be passing by and make an impulse buy without knowing they've probably spent a dozen such coins in the last year. Doesn't matter what anyone says...the coins still warrant no premium value and should not be selling for premium values. And they wouldn't be if the people buying them were educated, and the people selling them were educated and quit doing it.
There is an actual market, then there is a junk market. The actual market is a large group of people involved in finding stuff of value, stuff you cannot find every day with a little effort. It is stuff that is scarce and neat and has a story behind it. The junk market is an even larger group of people who fill binders with pocket change, don't understand how their damaged coins could not have been damaged in the minting process, and will buy anything "neat" for a buck just to add it to their book of oddities.
The educated error collector decides to sell their collection and there's a group of people to sell them to, usually at some profit because some of the pieces they might have are ones that are extremely difficult to locate and there are a number of people looking for them. The uneducated junk market collector takes binder after binder to sell and cannot get anything more than face value for their collection of oddities. I see it all the time, and am trying to educate people to this effect. Graduate beyond the junk and start dealing with the real deal. It will benefit you in the long run to learn the minting process, see a bunch of errors, buy a few, then start looking for them. If you don't know what you are looking for you won't find them. If you haven't absorbed the minting process and haven't seen the errors it produces, then you won't know what you are looking for. Simple as that.
