Hello everyone,

I bought a new digital microscope. I just started using it today so im still getting the hang of it. I need to know if what I'm seeing are double die marks on these coins and how much they could be worth. I will list them below.

Dimes:

  • 1984 P Roosevelt dime double die
  • 1947 Silver Roosevelt dime no mint mark double die. Silver around entire ring and weighs 2.5g.
  • 2001 P Roosevelt dime - I don't see a double die but need to confirm for coin owner
  • 1981 D Roosevelt dime double die

Quarters:

  • 1776-1976 D Bicentennial Quarter double die. There's also a line cutting across all the letters all around the coin in a circle, and lines on the hat.
  • 2021 D Delaware Quarter double die.

    None of those coins are doubled die varieties.

    I've looked at your other posts and you don't have a good eye for varieties and errors in general. The good news is that there is no requirement for coin collectors to search for any of these. Just enjoy your coins as is and don't worry about varieties and errors.

    Thank you for your input. My post clearly says I'm new to this and that is the whole point of the post. However, your feedback is not constructive. Thus, not providing me with any helpful information I could learn from.

    Sometimes, the most constructive feedback anyone can receive is to be told when they are going down the wrong path.

    Trust me, finding varieties and errors is not for you. Don't give it another thought. Hope you find some other aspect of coin collecting that you enjoy.

    First, it is "doubled die"

    Second, DDs don't just appear on random coins. There are known DDs on coins of certain dates/mintmarks. Various online resources will show photos of those. Your coins must match those exactly.

    You must also learn the difference between a doubled die and mechanical/machine doubling, which is infinitely more common, and worthless.

    Your new digital microscopic will probably turn out to be a time waster for you. You will be spending far too much time scrutinizing nothing.

    If you want to find more errors/varieties, look at more coins, don't look at your coins more closely.

    You are presumably fairly young and have good eyesight. Get rolls or boxes of coins from the bank and go through them quickly. Keep a list of known varieties such as doubled dies, and only scrutinize coins of those dates/mintmarks. For all other coins, check quickly for errors, such as clipped planchets, die cracks, filled dies, etc.

    One of your questions was about the supposed value of your coins. That suggests that someone has told you that you can make money by scrutinizing your pocket change for errors. That is very unproductive advice.

    Thank you for the advice. I really appreciate it and the detailed explanation. So from what I'm understanding, the doubled dies aren't random
    but have to match where they're shown to be. For eg, if it was found on letters A and E of a certain coin, my coin should also have it on A and E. Also, that what I have found are just mechanical doubling (which I was told meant double dies but I guess not) and have no value.

    Although we're using different terms, don't both essentially look the same when it comes to mechanical doubling or a doubled die?

    I've been going through a bucket of coins and watching videos on YouTube explaining how coins were graded and what they were valued at.

    DD and MD are entirely different in appearance (when you know what to look for) and in origin.

    DD is an anomaly on the die that will be repeated exactly on each coin.

    MD is sloppy workmanship as the die bounces or the coin moves during the striking/ejection process.

    I don't have it myself but others have posted elsewhere a graphic that shows the difference in appearance.

    Thank you so much. That makes perfect sense. And I thought all silver coins had value for simply being made of silver, such as the silver dime mentioned above. This is very helpful. I understand what to do now and won't give up. Have a blessed day.

    Yes, they do. They have value for their silver content, approximately $3.80 right now for a silver dime.
