One million dollars? No really, you need to be more specific. What error, what year, and what condition??
What's a major error? Mulistruck? Huge capped die? Broadstruck? Broackage? Unplated? Year? Mint mark? Condition? TPG?
If you think your coin is an error, a picture is needed, there are multiple factors involved, you can't just give a price, also :welcome: to the forums.
We on top is bad we on the bottom is up side down. tsu under the date and much more. As for the date cant say untill I have it graded
I'm having a little trouble understanding. Do you have a picture if you are talking about a coin you have?
Agreed, post a picture before you do anything else, I know I would hate to spend money to get something graded, and then find out its not a true error.
PCGS is good, but without seeing a picture of your coin, there are better ways to spend money. If you post pictures, we can give you better answers
Sending a coin for grading can be around 75-100 dollars once everything is calculated, it would be best to have a picture to put here, so you know if its even worth it.
CONECA will authenticate your error (or let you know it is not an error) for a whole lot cheaper than PCGS.
