I was going to ask for some references supporting this, but I think your original thread at CU pretty much covers it:...
From the discussions I've read here, that's not necessarily true. I have the impression that the traces of cleaning stick around even after a good...
Don't panic. If this is what it is, the mercury is bound -- "amalgamated", or alloyed -- into the surface. The only way to get a toxic amount out...
Maybe they tried to hit "6" and their finger slipped and hit the "5" right afterward.
...with the possible exception of the person who toned the coin. :)
Not old-school enough. My inner five- or six-year-old, and the books he learned from, counts "F, VF, XF".
Looking at all those lines, I'm thinking it stands for "Brushed Up".
That's... just... I... When I was maybe five or six years old, my grandparents were letting us kids look through (and sometimes choose from)...
Here's another seller with the same crayon box, and no mention of AT in the description.
Liquid mercury was, in fact, used as a purgative -- it's not absorbed much at all. Mercury vapor, on the other hand, is bad news. And...
You've already had your answer. Are you fishing for an answer that supports what you wrote on your test/homework? :) The question is ill-posed....
Yes, and Newton's Second Law of Motion states that the acceleration of an object is proportional to force and inversely proportional to its mass....
Huh. So why haven't they gotten to "melthelegend123"/"mel-ko"/"that lady with the purple crayon coins"?
Of course you did. Otherwise, you wouldn't be posting here. It's dumb to make coins with a composition that's optimized for toxicity -- not only...
Note the vertical scales in both of those graphs. That "dramatic drop" in the top graph represents about a 7.5% decrease from peak to trough, and...
Note that the auction description labels this as "AT", and describes it as a "fairly inexpensive alternative to graded coins" -- neatly dodging...
Nope. A troy pound is 12 troy ounces, and an avoirdupois pound is 16 avoirdupois ounces. 16 troy ounces isn't any sort of pound at all, except for...
Yep, the Type 1 gold dollar had the smallest diameter of all US coins. Type 2 and later were 15mm. Lowest mass (weight) for a US coin would be...
Okay, I'm one other person on CoinTalk who got that. Anyone else? :)
Actually, if it would stay in that valence state (0), it wouldn't have any effect. The problem is that stomach acid and galvanic activity oxidize...
Separate names with a comma.
