After you create your account, click “Sync” to begin uploading your collection. Graded and authenticated items can be inputted via “Sync”, utilizing image scans, serial numbers, or by uploading a CSV file. Raw or not-yet-authenticated items can only be inputted through a CSV file, at the moment. You can simply drag and drop your items (in bulk or one-by-one) onto the page, or manually enter in serial number(s). Once all items are in, click “Sync Collection.” Mascot has integrations with all leading grading companies to automatically pull in as much metadata on your items as possible.
