PCGS has estimated the total number of Proof 1850 large cents (including both varieties) as 10. They have assigned grades to examples six times, with the possibility that there could be duplicate entries of the same coins, which would be nearly impossible to avoid. NGC has three grading records for the date, as of our writing. Assuming these are all different pieces, it suggests that the records of Walter Breen and Denis Loring are very accurate and that the number of N-11 Proofs extant places the variety solidly in the Rarity-7 range for this special format. Breen listed five specific examples, and “one other reported.” The Loring records include seven distinct specimens and some older appearances that are likely coins that are counted and confirmed from more recent offerings.

The example to the left was sold by Stack's Bowers Galleries in the July 2015 Baltimore Auction, where it realized $82,250.
