Almost any nice choice unc to gem coins from '05 to '10 should be winners since mint sets are SF. I'd pay especial attention to dimes and halfs.
Speaking of which, the cost of transactions will fall dramatically and their speed increase with fewer credit card transactions. There should be...
Don't look for this change to actually happen though because a workable currency system will hurt credit card companies and credit card companies...
I think everyone including collectors are missing the big picture and the real opportunities here. If they eliminate the wasteful cent there's a...
It's an extremely nice specimen. Its characteristics and slightly PL nature are highly consistent with a mint set coin and would be in the top...
I couldn't have helped even if I saw this in time but I do like the 100Y cu/ ni coins. The first couple years there were no mint sets and...
I use denatured alcohol but can't swear by it. It's a cheaper alternative but I don't have enough experience with it yet to recommend it.

I don't have much doubt you're right. Water will get down in between the atomic lattice of the metal and can take significant energy to dislodge....
Olive oil works only on copper and bronze (tin)(maybe aluminum). It only helps to remove encrustations. I use a locust thorn or tooth pick to...
Olive oil is best for soaking dirt off coins but should not be used on uncs or proofs. Mineral oil is OK but a second choice. I have very...
It is apparently a hammered bubble.
I believe these will still bring $14 wholesale but there probably aren't any active buyers now. If the are Denvers be sure to check the top of...
Yes, this is the mottled corrosion to which I referred earlier. It is very difficult to remove and this is the last step before it becomes...
Thanks for the kind words. I don't really know that it's actually PVC in the inner layers of plastic and this is largely assumption based on...
I just have to beg to differ; I believe all real knowledge is experience. You raise some interesting points but my experience in these areas is...
It's mostly just experience. From very early on it was obvious that what mints do and what they say don't really match. In most cases it's not...
I avoid talking about US coins in this forum and it's difficult to provide a comprehensive answer without doing so. US mint packaging material...
The bad news is that the mint packaging for '68 to '84 mint sets has a thin inner layer of PVC. The good news is that most coins can still be...
There won't be any change until we get campaign finance reform. Congress gets richer the more contentious the issue but they still care about a...
Separate names with a comma.
