What Is My Item Worth? — A Guide to Valuing Items for Barter

Research the Market Price First

Search for your exact item (or the closest equivalent) on second-hand platforms like Carrot Market or Bunjang to see real transaction prices from the last 30 days. Focus on completed sales, not listed prices — sellers often list higher than what buyers actually pay. This gives you an objective baseline.

Apply Depreciation

Electronics typically sell for 50–70% of retail, dropping sharply just before or after a new model launch. Clothing runs 10–50% of retail depending on brand and condition. Furniture is usually 30–60% of retail and drops further if it needs reassembly. Original receipts or warranty cards can add roughly 10–15% to perceived value.

Condition Grade Reference

• S-grade (sealed/brand new): 80–90% of market value
• A-grade (like new, no visible wear): 65–75% of market value
• B-grade (light signs of use): 45–60% of market value
• C-grade (noticeable scratches or partial malfunction): 20–40% of market value

Use Nada Market's Silver & Gold Conversion

Enter a price in Korean Won and Nada Market converts it into silver (Ag) and gold (Au) grams using live market rates. This shared unit makes it much easier to compare completely different items. For example, 'my AirPods (₩50,000 ≈ 50g silver) and your wireless mouse (₩50,000 ≈ 50g silver)' immediately shows the swap is fair, lowering negotiation friction.

Separate Emotional Value from Market Value

Even if you have strong attachment to an item, its market value is objective. Gifts and keepsakes are no exception. On the other hand, rare, discontinued, or limited-edition items can legitimately fetch more than similar second-hand goods. When in doubt, ask in the community forum — someone will know the going rate for almost any item.
