The danger is they identified a foreign substance on the coin. If you do not conserve it I doubt you will receive a clean grade.
Yes, that is what I have heard too. One of my Byzantine solidi looks similar. Many times dealers clean this off to give a more clean gold...
There shouldn't be toning on gold. Are you sure its not PVC contamination?
.pdf is safe Larry. You are right to be concerned about opening attachments, but pdf's cannot harbor viruses as far as I know. Nice article OP.
Why the heck would they make the denomination $100 for a one ounce coin? That makes no sense. Good grief, at least keep consistency and make all...
If it is bronze disease, do yourself a favor and contact badthad here for his product that treats it. A simply treatment can stop this from...
It hasn't been legal for years no sir. Anyone who has any basis to claim "protected" status believes they are above anyone else's rights anymore.

Both are primarily driven by industrial demand, not jewelry or investment. More uncertainty of economic demand due to Greece is hampering prices...
But is there this handful of geeks who want it enough to pay that much? That is the question. How many Postumus reverse variety collectors are...
I agree with Doug. Rarity is a weird little thing in ancients, no? I find desirability of the type to be the overarching price driver. Case in...
For wood, the concern will always be outgassing and toning of the coins, (whether in slabs or not). The only decent wood I have ever heard of is...
I like everything about the coin. Excellent bronze.
Greece is not a real proxy for the US. They owe way more as a percent of GDP than we do, they have like 55% of their population working for the...
Btw Eddie, I apologize for the tone of my earlier post. It came out harsher than I intended. I still believe there is a theoretical difference...
So if PCGS gives it a grade, that is the end of the discussion? No one should try to learn to grade, since it won't matter anyway because they are...
Make that coin a 95 and see if that coin resides in that holder. THAT is the difference between market grading and rarity bump. All flowing hairs...
I agree. First thought Seleucid, second thought looks absolutely genuine. I agree JA probably knows this one on sight.
Contact Badthad. Buy his product. If its not BD his product will not react with it or hurt it. I always throw some of his stuff on if I am in doubt.
To further clarify, (sometimes Doug is a little too brief), only precious metal coins did they ever try to weight adjust. Copper coins, from the...
