Bookkeeping for comic book, trading card, and collectibles retailers, including specific-identification inventory costing, consignment, and hobby-vs-business tax classification
Average-cost and FIFO inventory methods misstate margins when every item is unique. How antiquarian booksellers use specific-identification inventory — per-copy cost basis, proportional lot allocation, condition-driven write-downs, and provenance records — to keep accurate books on one-of-a-kind stock.
How comic and TCG shops should book consignment splits, buylist store credit, and graded-card cost basis — consigned goods stay off the balance sheet, store credit is a liability until redeemed, and high-value singles need specific identification, not average costing. Plus where the IRS draws the hobby-vs-dealer line, from the nine-factor §1.183-2(b) test to the 28% collectibles rate.
