Are these quarters the product of a mint error??

i went ahead and posted both of these quarters in the same thread because they look like they both have the same kind of irregularities present.

*The rim on both coins is flattened/smashed or not there at all.
* The edges are still mostly reeded.
* On the obverse of the Michigan quarter, there is a lump(?? bulge??) on Washington's neck as well as above the back of his head at about 2oclock.
*They both have a grainy texture to them as well as some gouges/slashes
*Both quarters are certainly thinner than your average quarter (especially the 1998).
The Michigan quarter weighs 5.50g and the 1998 weighs 5.73g. Then i also weighed a regular Wisconsin state quarter and it weighed 5.65g. (i did that because my scale needs calibrating (its a couple 100ths of a gram off but i dont have the weights to calibrate it so i figured I'd just compare all the quarters based on what my scale was telling me atm.)

that's about all the info i have i suppose..
Any thoughts/info would be much appreciated. Thanks!

Not sure what caused all the damage, but they are not mint errors.

 

thanks, i appreciate your reply!

 

Do know the total provenance of each quarter?
or are they from pocket change?

Remember, quarters are put into circulation and all havoc can occur on them from parking lot scruffs to hammering, etc.

Instead of thinking what "errors" these are, try to learn how coins are created, and think what "damage" this is.

 

they are indeed just pocket change.

 

I guess the thing that got me thinking possible mint error was the lumps/mounds or what have you that are on the obv. of the Michigan quarter. you can hardly see them in the photo though. I'd try and take another photo to show that aspect more clearly but i doubt it would change any opinions.
I really appreciate feedback though. Thanks for baring with me while I begin to learn more about errors and the minting process in general .

 

Just circulation wear and tear damage.

If one day you do find a true Mint Error please DO NOT use tweezers to hold your coin. That is a big no no in the coin collecting hobby.

Here is a website to better educate you on true Mint Errors

if you look at the Michigan quarter you can see the edge where the edges was pushed in from some traumatic event.

If you look to the immediate left of the bulge on George's neck, you can see where metal was displaced/ pushed towards the bulge.

In other areas you can see where it was whacked from atop and the backside shows the scars.

Anytime metal is disturbed it either moves or can fall off. You can move surface metal, or move and bunch up the surface, or whack it and maybe affect the opposite side as your coin shows.

Ever watch that show on the History channel where they makes knives/swords out of a lump of metal ?

 

Looks a little like it was run over by the transporter at Launch Complex 39 at the Cape.

 

Generally speaking it is usually wise to avoid handing coins with a roach clip.

 

Those coins appear to have been hammered on with various steel tools, etc.
Here is an article about people in the UK intentionally hammering coins into old trees for good luck - strange but true

Not flat enough.
