Possible errors?

[mjammann]

First off, I want to begin by stating that I am just getting into coins. I recently inherited several coins in white cardboard wrappers with notes and a microscope that was likely used to examine them. I have taken some photos of some of the, but I honestly have little idea what I'm looking at besides the notes on the coins.

These here are three of what I think are the most interesting, but again, I've got absolutely no idea what I'm looking at. I will try and describe what I saw and mark them properly.

Any help, advice or direction would be very helpful Thank you in advance:

One of the coin is a 1989 Dime that was marked as having some doubling on the back in the inscription "United States of America"

The second is a Quarter with what looks like bubble letters around the year and "in god we trust"

I am doing my best to learn as there are many -many- more coins like this that I have, but I'm unsure if there is any value in investigating further.

Thank you in advance,

The doubling that you are showing in your images is caused by the coin taking a jiggle in the collar. Its called MD "machine doubling "
notice that the doubling is one sided and flat shelf like doubling.
never the less since you're new and unfamiliar with what you're actually seeing please post any other specimens that you question.
Should you had something unique feel free tp PM me and I will take a look at what you found.
Roosevelt dimes tend to have either md or die deterioration. ...as dies are worked punching out thousands of coins.
Best Regards

Marie coin errors are mint errors such as mis strkes clips, off center, multiple strikes, etc.

varieties are doubled dies, repunched dates or repunched mint marks, misplaced dates...

im sure over time the terminology will catch up with your interest level.

yes, the reverse has worthless doubling as Paddy54 has stated. Its lower, shelf or step like. Doubled dies are made when a steel working die received more than one impression onto a working die. The trick here is to understand that most of the impressions were at the same strength. The press would impress the working dies, sinking the design into the working die. The impressions on the working die should have been at the same depth. so, when a working die strikes a coin, what is sunk into the working die, will be raised on the coin.

There are many people who have a difficult time knowing the difference between worthless doubling and a true doubled die. Also note, that from 1996 to present, the mint went to a single squeeze technology. By doing so, there are less doubled dies from 1996 to now.

For the record, if you will. The CONECA forum rules state that it should be one coin per post. They say that it cuts down on confusion, and allows people to use the forum search function with more positive results. Just an FYI for future posts.
