Every Consensus Comp rests on real, recent sales a person checked. Here's how.
Step 1
Real sale
Each comp cites a sold listing.
Step 2
Blind vote
Nobody sees others' comps while live.
Step 3
Reviewer check
A person checks every comp.
Step 4
Approved = value
Their middle, newer sales weighted more.
1. Every comp cites a real sale
A comp is a real sale of the card from the last 5 years (newer sales count most; over a year old is labeled): a link or screenshot of the sold listing, plus the site, date and how it sold. Guesses and asking prices don't count.
Best Offer sales need proof of the accepted price, such as a 130point link. eBay shows the asking price, which can be much higher.
2. Voting is blind
Comps open when a card joins the Comp Night lineup. On the show (8 p.m. Central) it's live about 2 minutes, then late comps stay open 7 more days. Until its turn ends, nobody sees others' amounts, sites or dates, so each comp is an independent call. Owners can't comp their own cards. Call it guesses are separate: no proof, and they never count toward a value.
3. A reviewer checks every comp
Nothing counts until a Crowd Comp reviewer approves it. Reviewers check:
• Same card: set, number, parallel and print run
• Same grade and grading company (or raw)
• Another print run: the same card in a real numbered parallel, not a jersey-number serial
• The price is what was actually paid
• A real sale: not a lot, not cancelled or unpaid, and the buyer has feedback
Reviewers never review their own work: their own comps, comps on their cards, or sales they found. Only Crowd Comp's owner can review anything. Trading card game slabs go to reviewers who know printings and stamps. Brand-new accounts get a closer look. Three denied comps in a week pause a collector's comps for 24 hours.
What the Value box shows
• Value: the gold number, with its range bar from low to high
• Score ring: how sure it is, with its label (Low, Medium, High)
• Comps: how many reviewed sales back it
• Newest: how recent the latest one is
• Match: how close they are to this exact card
• Agree: how tightly the prices agree
• Similar comps are adjusted by a set table before they count
4. Each sale counts once
A sale counts once per card, whether it's filed by hand or cited from our reviewed sales, and can't count again for 90 days. Citing a reviewed sale counts without another review, as soon as the card's turn ends.
5. When a value is set, and how sure it is
A Consensus Comp is the middle of the approved comps once enough real sales agree, with newer sales counting more. A collector's record (comps approved, and how close they came to others') makes their comps count a little more or less. A sale at another grade or print run counts as a third of a comp, converted with our multipliers (at least one comp must be this exact card and grade). Confidence (Low, Medium, High) reflects how many comps there are, how recent they are and how closely they agree. Each value shows its range, comp count and sale dates. We flag values older than 30 days (14 for trading card games) and values that newer reviewed sales differ from by 25% or more.
6. What a Consensus Comp is, and isn't
It's crowd opinion from cited, reviewed sales. It isn't an appraisal, grade or authentication, and isn't for insurance, tax or lending. A Comp Report shows the Consensus value and its reviewed sales, not authenticity. Anyone can check one by its number or QR code.

7. Fair play
A board spot buys the crowd's time, nothing more: no prizes or drawings tied to paid entries. Status points come from approved work and can't be bought, sold or cashed out. If a card's entry ends without a Consensus value, its credits come back. Call it earns nothing but a place on the leaderboard, and calls that are way off pause it.
8. Names and trademarks
Crowd Comp isn't affiliated with, endorsed or sponsored by eBay, PSA, Beckett (BGS), SGC, CGC, TAG, any card maker or any game publisher. Their names are used only to describe cards, grades and sales.
