NGC Coin Census Scraper — Population / Grade Data

Get NGC coin census (population report) data — how many coins are graded at each NGC grade — 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.

What you get

For each coin in a series:

FieldDescription
descriptionHuman-readable coin label, e.g. 1909-S VDB 1C MS RD
countryCensus category / country (e.g. United States)
coinTypeDenomination category (e.g. Cents)
seriesSeries / group (e.g. Lincoln Cents)
year, denomination, mintMark, strike, variety, designationCoin attributes (designation = MS, PF, etc.)
populationByGradeObject mapping grade label → count, e.g. { "MS/PF 70": 12, "MS/PF 69": 340, ... } — only non-zero grades are included
totalPopTotal coins graded for this coin
listingUrlLink to the NGC census page for the series
coinId, populationIdNGC identifiers

Input

Navigate the census the same way the NGC website does: Country → Coin Type → Series.

{
"country": "United States",
"coinType": "Cents",
"series": "Lincoln",
"maxResults": 1000
}
FieldDescription
countryCountry / census category. Default: United States
coinTypeDenomination category (e.g. Cents, Dollars, Gold Double Eagles). Blank = all types
seriesSeries name filter (substring). Blank = all series in the coin type
groupIdAdvanced: scrape one series directly by its NGC research group ID
maxResultsMax coin rows (0 = unlimited). Default 1000
maxSeriesMax number of series to scrape (0 = unlimited)
proxyConfigurationRESIDENTIAL proxy is used by default (NGC blocks datacenter IPs)

Examples

Scrape one specific series directly:

{ "groupId": 82 }

All Morgan / Peace dollars:

{ "country": "United States", "coinType": "Dollars", "series": "Morgan" }

Notes

  • Data comes from NGC's public census. Use the residential proxy (default) — NGC blocks datacenter IPs.
  • populationByGrade only lists grades with a non-zero count, keeping output compact.
  • NGC grade scale includes Plus (+) and Star () designations, and Details buckets for coins with problems.
