NGC Coin Census Scraper โ Population / Grade Data
Get NGC coin census (population report) data โ how many coins are graded at each NGC grade โ for any country, coin type, or series. This is the numismatic equivalent of a card population report: for every coin (year, mint mark, variety) it returns the full grade breakdown, from MS/PF 70 down through circulated grades and Details (problem-coin) buckets, plus the total graded population.
Great for coin dealers, collectors, registry-set builders, price-guide makers, and anyone analyzing rarity and grade distribution.
