Hi John Again JMO...I don't have to be Einstein to figure out the value of state quarter rolls, President dollars and Sacagawea.
The difficulty in pricing (very) low mintage coins like this is that the auction records in circ grades can sometimes exceed unc grades. For the purposes of this month's adjustment I bumped the 1871's to $650 in XF and $700 in AU. I have some other pricing data where an NGC XF45 sold (retail) for $925 in the last 12 months. Also, a strong number but we err on the side of being careful where we lack complete data.
