Today I was focused on a doubled pennies. It is very difficult as I have not found one yet. I posted pictures of 3 separate pennies, I believe they are all machine doubling, am I correct.
Thank you it is very hard to learn if I can't find one to compare it to. I have the website but it does not seem to help me. Thanks again
The good news Marie...you are experiencing what most folks experience. Don't worry though. Once you find a true DD, you will start to develop the eye and it comes to speed quickly. You'll likely hear your inner voice chuckle. So keep at it and it'll happen soon enough!!
You are certainly looking in the right spot. Like @Kevin Mader said, when you see the real deal it will jump out at you.
