Q1: How do marketplace transaction fees affect short-term flipping profits?
Standard platform fees on eBay and similar consignment portals average between 12% and 14%, plus processing fees and shipping materials. To maintain positive margins, plan for at least a 25% price increase on any card simply to break even after packaging and sales commissions.
Q2: Is grading raw cards always necessary for short-term flips?
No. Selling cards raw during an intense trade-deadline hype cycle avoids grading fees, shipping delays, and the risk of unexpected 9s. Raw cards often command strong premiums during the immediate 72-hour window following an NBA trade, when collectors want quick shipments before the market cools.
Q3: Why are base cards considered high-risk in the modern market?
Modern card production levels have produced an overabundance of standard base cards. Without artificial serial numbering or genuine scarcity, secondary supply completely outstrips demand once initial player hype subsides, making long-term value retention almost impossible.
