I've worked with Toluene on and off for years. Always under a fume hood, but I never had a problem with the odor.
@Conder101 Check out his pic of the readout in post #8. The program listed Sn over some of the peaks on the chart, but the readout listed Ir. I...
I agree with your comments. Generally, I would conclude that the user left some residual organic material or didn't rinse the residue off the...
Lots of anecdotal stories but no science to support that dipping and rinsing have any ill effects on copper
The area across the shoulder and on the back look like laminations to me. I also think the area along the rim is a lamination and during...
The mint label seems like a likely culprit I don't think cellophane degrades into nasty things, but I know enough just enough organic chemistry...

Until the coins come out:D Seriously, Overnight is probably fine
That explains a lot. Stick around coin talk and you can learn a lot about the minting and die making process. I believe Wexler's Doubled die web...
You ARE NOT seeing more than a "5". Please go back and read post #88. You will not get a more respected opinion on error coins in all of...
It's a misaligned die (MAD). They really don't carry a premium over face value, but yours is pretty cool and I would keep it if I found it in change
Regarding the Lower right coin, check Bavaria 1621 3 Kreuzer or some similar billon denomination. I don't have my references in front of me but...
