BTC Star Buy Rating: The BTC star rating algorithm considers multiple criteria including price percent change (compared to the average price of the overall list), average dollars per bid, bid rating score, and power ranking numbers. BTC Star Rated cards are prospective buy opportunities.

Sports Card Analysis: The higher the Bid Rating (BR) or List Ranking (LR) number - the hotter the card is or more valuable.

Bid Rating Number: The Bid Rating (BR) score system measures bid count behavior activity for an item and analyzes it against all other auction items listed. Simply speaking any BTC Bid Rating above 1.0 illustrates robust or better than average bidding activity.

Active Bid Icon: Active user bidding with above average bid engagement. The higher the bid rating the hotter the card.

Power Ranking Number: The Power Ranking (PR) rating system analyzes each card (or card product) against the queried list’s average cost per card. A Power Ranking (PR) number is assigned to each card. The higher the number the more valuable the card.
