Charles, Thanks for the info on the flow lines from grease. It makes good sense, I just hadn't thought about it. Jim
Don't use the coin dip. If the acetone is contaminated ( maybe the coin itself) , it may deposit a thin film on the coin as it evaporates. Try...
Can anyone say "MARKET GRADING" ?? Adams-Carter Class III dollar, graded "extremely fine" by Eric P. Newman and Kenneth E. Bressett, "EF,...
There is a chance it is real "enamel" rather than enamel paint. Makes it a higher class art object, but definitely won't respond to any chemical...
The darker areas are mostly shadows. Take a look again at the whole coin photo. In the coin in question, the darker area is depressed slightly...
Neal, what is your goal for the coins you expect to holder? Just for long term safety with the minimal amount of time checking their progress, Or...
here is a close up of the area of the affected one and also a normal one.The "squiggle" below the "19" that looks like my 401K is a die gouge that...

Many of the plastic holders can develop static charge when being handled by cloth which might actually increase adherence of dust. That is why the...
Welcome to the forum! The website you listed is a very informative one. The image you asked about is an example of strike doubling damage or...
I just pull one paper side off of corrugated cardboard from a box and brush the peaks with rubber cement and allow to dry. It the adheres to...

I agree with Chuck on this as I use a B & L binocular stereo zoom 7-30X scope ( lab surplus) and it has one eyepiece adjustable so I can use it...
From general observation, the "S" mint mark on the 1992S Kennedy doesn't seem to match the symmetry of either of the ones you indicate. I have...
