Yes, a learning opportunity. Take a close look at that reverse; that's a classic, if a bit exaggerated, example of "sinking devices", where the...
Good choice!
They don't. I'm sorry I wasn't clearer in my post. NGC and PCGS will optionally put a letter grade on detail coins, at least for some coins....
A few more notes: PCGS and NGC (I think) give you the option of having a letter grade appear on a details slab, or just having the slab say...
Sharper and larger pictures will help, but this looks like it might be acid damage. Welcome to CoinTalk!
What do you like to observe? The "moon permitting" comment makes me think of extended objects rather than planets, multiple stars, or variables...
I would've jumped on that at a dollar. I'd study the date at great length to see if I could nail it down. If it's just not possible, I'd give it a...
If I ever thought there was an event so sad or tragic that someone wouldn't try to make a buck off of it, the "9/11 commemorative" painted coins...
If you're spending thousands on coins, shell out tens of dollars for capsules or soft archival flips. Better albums (like Dansco) won't degrade...
Yeah, I had that experience with another dollar coin, although it was worth it to get the last of the goo off that one. It appears that this coin...
Hard to rule out anything from this, except a 4 seems unlikely. And, of course, 0, 1, and 2 are right out.
Looks more like a 5 than any other digit to me. But we're deep in "seeing-what-we-want-to-see" territory here...
That's a difference in the wrong direction. 1964 90% coins weigh 12.5g (+/- 0.259g), 40% coins weigh 11.5g (+/- 0.4g), and clad coins weigh 11.34g...
That looks like a normal clad edge to me. When the blank is punched out of the strip, the top cladding layer gets dragged down across the copper...
Emphasis on "away" -- something combines with the metal and takes it away from its original position on the coin. And once that happens, it can't...
Unless, of course, he cut the supervisor(s) in on the deal.
That's what cardboard albums do. The sulfur and/or acid in the paper reacts with the parts of the coins that are exposed to it. The hotter and...
No, iodine from the pen reacts with starch in wood-based paper, which includes most printer paper. Currency paper doesn't have that (made from...
If you're trying to save for a car, spending on coins is going in the wrong direction. You're about as likely to "hit the jackpot" buying coins...
That was essentially what I was going to say. Whatever note it was, if any, it fooled both me and the person or machine that got it next.
