From the images provided, I can see dates on these quarters and that is about all. But keep in mind that these coins are 50 years old. So they would have been used in vending machine for years, flattening in the motto devices. Also at that time, there were a lot if master hub swelling and master hub wear. So these devices could have been distorted at the time when they were struck. It would be more helpful to look at listed doubled dies during these years to see what to look for on doubled dies. That way you would know where/what/how these were showing hub doubling. Damage to coins and Machine Doubling can happen any year/denomination. Knowing what to look for would be more helpful, than guessing what you think would be doubling. So take time and look at the one year each day and go through the different doubled dies that are listed, to see why they are doubled dies. For instance. 1970 Cents had DDO's that were different than any other year. What do they look like? Something to look at. While some of the doubled dies are like other years, this year had some that were really different that year. So when traveling, we used to look at a map to see how to travel. Same for collecting ready what is already listed can help you see what to look for on doubled dies that year. Knowing what has happened during that time period, will help train more than guessing. That would be like not looking at a map and going the wrong direction to get somewhere. Just a suggestion. Give it a try.
