Exchange Market & Auction House
Two separate selling systems. Exchange = day-to-day fixed-price listings. Auction = weekly bidding for high-value items. Different fees, different strategies.
Exchange Market — rules
Listing mechanics
- Slot limit: 8 slots (Whitesmith gets bonus slots — only class that does)
- Listing duration: 24 hours; unsold items return to your inventory
- Stocking fee: 1% of current price (paid up-front when listing)
- Sale tax: 9% on the sale price
- Net to seller: ~90% of sale price (after the 9% tax; 1% stocking fee was already paid)
Effective margin
On a 1,000,000 zeny listing:
- Stocking fee: 10,000 zeny up-front
- If sold: 1,000,000 − 90,000 (9% tax) = 910,000 zeny received
- Effective margin: 900,000 zeny net (1,000,000 − 10,000 − 90,000)
- Always factor 10% combined fees into your flip math
What you can list
- Most tradeable items (gear, cards, materials, blueprints, headgear, etc.)
- Premium Cards — F2P players buy these to convert zeny → BCC
- Some bind-on-pickup items cannot be listed

Auction House — rules
When and how
- Registration window: ends every Friday
- Cannot register: in the 30 minutes before auction starts
- Starting bid: 60% of current Exchange Price
- Bidding currency options:
- Zeny — direct
- BCC — at the rate 10,000 Zeny = 1 BCC
- Final settlement: sellers receive the final winning bid in zeny
- No fees on the bidding side itself (registration fee may apply —

What goes to auction
- High-value items that don’t fit Exchange’s pricing model: rare cards, MVP cards, high-refine gear, limited costumes
- Items where price discovery via bidding gives sellers a better outcome than fixed-price listing
Notable auction sales (historical)
- Ghostring Card sold for ~318,000 PHP equivalent in 2018
- High-end mounts have sold for tens of thousands of USD equivalent
- Endgame economy is very real — top items command real-money equivalents
Listing strategy (Exchange)
Pricing
- Check current Exchange price: open the same item to see live listings
- Undercut by ~5–10% if you want a quick sale; match the floor for a slow but full-price sale
- Time-of-day matters: SEA peak hours (evenings) for fast turnover; off-hours for less competition on listings
What to list
- Always: cards, blueprints, rare drops, refined gear
- Sometimes: stacked materials in bulk — list at a slight markup over NPC vendor price
- Don’t bother: junk drops < ~10K each; auto-sell instead
Whitesmith advantage
- Extra Exchange slots → more parallel listings → more flow
- Critical for any serious flipper; alt-Whitesmith pays for itself
Premium Card path (zeny → BCC for F2P)
- Have surplus zeny
- Browse Exchange for Premium Cards (BCC items listed by other players)
- Pay in zeny → receive BCC equivalent
- Sellers do the reverse: top up real money → list Premium Cards → receive zeny
The rate floats with supply/demand but tends toward 10,000 Zeny ≈ 1 BCC as the auction rate sets a soft anchor. Premium-tier convenience items command a markup.
Common gotchas
- Forgetting the 10% combined fee when calculating profit
- Pricing without checking the market — costs you the sale (too high) or burns your spread (too low)
- Auction registration deadline — miss Friday cutoff = wait a week
- Listing a single item per slot — for stackables, list the largest stack you’d actually sell as one transaction (otherwise slot waste)
- Tax on Premium Cards too — converting zeny→BCC has the 10% spread baked in
Price tracking
- ROM Exchange (RoGuard embedded) — historical price charts for many items
- File your own price log per item under price-tracking.md
