I must be confused. I don't see a 'mostly filled' D, anywhere on the
dime. It certainly is not where the mintmark usually appears.

I have a 30 power loupe, and I don't see it
on the coin, but when I look at the picture, "it looks
as if there was a D".

I searched to see if there was filled die strikes
cataloged and found a statement about 264,000
strikes and half a million coins in collections. :-)

For now I consider it an optical illusion,
but I won't list the coin.

I think you can be pretty confident if you didn't see a D under that
much magnification it does not exist.

Actually, anything over 5x is good mostly for spotting and identifying
extremely tiny isolated details like whether a really small dot is perfectly
circular or slightly elliptical.

That means that super-magnification tends to lose the bigger picture of the
forest's patterns of trees. *These are better identified with low
magnification or the naked eye. *Once identified that way, closer
examination under higher power (especially with stereo microscopes) gets you
into the realm of nailing down specific die markers, looking for obscure
hints of counterfeiting, etc.

Has he tried that yet, and if he doesn't see the D, are there any
other possibilities?

* * * * I see the D on the existing images and with a 5 power
large diameter lens I use (the cross-hair focusing lens from
a WWII fighter plane gunsight).

* * * * It is a very classic D image with the bottom left
missing and a groove down the middle of the top,
but it may be a little too big to be a mint mark,
I will be trying to find images that show the size
relative to the other devices.

* * * *I bought a refurbished Olympus that focuses
down to 0.4 inches and made a hand-held copy
stand that seems to work good when the camera
is not acting up, the thing just has too many
bells and whistles. * * So if I find out anything
definite and get some better pictures I will
post them.

* * * *With only 264,000 strikes there should
not have many dies used, that is helpful.

* * * *My 1956P Lincoln with a die crack on the
forehead and a die chip on one side of the
crack that looks like ooze did not sell on
ebay, the picture didn't turn out good, but
I have a couple more examples where the
chip got bigger causing a bigger ooze. :-)

* * * *There was a couple of bidders on the

to ship rolls in a padded mailer for less

ask the first few buyers to let me know
if any coins get damaged.

56, 57 and 58 cents from somebody
posting here about 8 years ago, and
I opened them all, and some are really
nice, I like to expose them to the air
to see if they stay red and shiny.

Maybe your right and your 1916 Mercury is a Denver production, I am in
no way an expert on error or damaged coins. I'm just looking for a
discussion about coins
