Are coins that dont have an established double date(1955) worth more or less. I found in my collection a 1915 in really good condition with the double date. Sorry I dont have a cam that gets good enough pics and also the coin is in a glass frame.
No one is going to comment unless you can upload some kind of image, im not saying this to be rude im just trying to save you some time. When you are able to post some pics we will be more than happy to answer your questions regarding your coin.
I am not an error collector by any stretch of the imagination, but there are double die coins and there are coins with machine doubling. The machine doubling occurs every year and the coins are worth little if any above collector value for the base coin. Certain years (like 1955) have dies that get doubled and then there is a population of doubled die coins that might command a premium. If your coin is worn, it would be hard to distinguish machine doubling from an actual doubled die. Someone will know if there are doubled die varieties from that year. Good luck.
To answer your first part, a true Doubled die 1915 Lincoln would be a high price coin as none are known/verified. A close analogy would be the 1917 Doubled Die Obverse cent. Since variety collection wasn't well established at that time, high grades are very expensive, whereas well circulated may be in the hundred dollar range. But in any given month, 10s to 100s of 1917 DDO ( as per the seller) are listed on EBAY, almost every one is a case of Machine Doubling Damage with no extra value. If you hang around a while, you will find that the large majority of supposedly doubled die coins are MDD. That is why no one gets real excited at first until some photos are presented. We will be glad to help interpret your coins features when you can get a good photo of the date. Some use a magnifier in front of their cell phone or digital camera to bring the "macro " feature of their camera even larger. Take your time. Also remember that some times photographing at angles through certain glass, you can get a double image. Welcome to the Forum!! This is a MMD on the date , notice the right of the "2". It is flattened shelf like, Here is a photo of a 1917 DDO type 1. Notice how each doubled part, is about the same height, and where they end, there is separated serifs of the number. This one being so widely separated, the serifs are easy to see, but the reason I put it here is so you can see that each portion is about the same height, no flattened. Another with no doubt. Jim
Here is a PDF flyer from Coneca that does a great job explaing the differences in Doubled Dies and things that can appear as doubled dies http://hermes.csd.net/~coneca/content/StrikeDoublingFlyer-PDF.pdf
