Market and sales data on the League of Comic Geeks is primarily community-driven. Members help submit and moderate sales history to ensure accuracy with complete transparency.
Requirements for Sales Data:
Must be a completed sale of a single comic. No lots, bundles, etc.
Grades are not permitted for Raw comics. This is too subjective.
Signed comics are not permitted in sales data. These are outliers.
Newsstand Editions should be with their respective variant in our database, not mixed with Direct.
If the sale cannot be verified, it does not belong in our database.
At this time, only eBay and Heritage auctions are permitted. More will be added in time.
eBay "Best Offer Accepted" with final offer prices unknown are not permitted.
USD sales are all that is permitted at this time to avoid currency exchange variances, unless the auction site provides this exchange.
Reprint sales must be associated to their specific variant listing, not the main cover.

How are points distributed for sales data contributions?
Initial submission of a completed sale is worth 3 points to the Submitter
Review (verification or flagging) of a submitted contribution is worth 2 points to the Reviewer
If the sales data is verified, the initial Submitter receives an additional 2 points
If the sales data is incorrect or fraudulent, the initial Submitter receives a penalty of 10 points
At certain (hidden) thresholds, these penalties begin to multiply to thwart abuse - eventually resulting in a ban from contributions or potentially account suspension
