SGC Pop Report Scraper — Graded Card Population Data

Get SGC (Sportscard Guaranty Company) graded-card population data for an entire set in one run. SGC is one of the top trading-card grading companies, and its Pop Report tracks how many copies of each card exist at each grade.

Returns a structured, per-card grade breakdown including SGC's full scale:

• Pristine 10 (the "gold label" top tier)
• Gem Mint 10
• Numeric grades 1 – 9.5 with half grades
• Authentic (cards graded but not numerically scored)
• Cumulative "population at grade or higher" counts
• A computed Gem Rate % (share graded Gem 10 / Pristine 10)

Covers Baseball, Basketball, Football, Hockey, Soccer, Boxing, Golf, Non-Sport, Pokemon, Racing, Tennis, Wrestling — plus the vintage T205 / T206 tobacco-card master pops.

Input

Finding exact set names

SGC's set-name search is protected by reCAPTCHA, so the most reliable workflow is:

1. Browse to gosgc.com/pop-report and search for your set.
2. Note the exact set name and sport shown.
3. Run this actor with cardSet + sport.
