AI market analysis

For buyers

Beware the inflated eBay asking median of $97,999; realistic grey market value for the 5164A-001 currently hovers between $60,000-$70,000. Target the lower end of this range, potentially around $60,000-$65,000, leveraging the noted 'low liquidity' to your advantage. Be prepared to negotiate aggressively, as the current eBay median reflects asking prices, not actual completed sales.

For sellers

Given 'low liquidity' and a wide spread between grey market ($60,000-$70,000) and eBay asking prices ($97,999), set your initial asking price judiciously to attract actual buyers. Aim for the top end of the established grey market range, perhaps $68,000-$72,000, to allow for negotiation while still reflecting its 'Rarity 8' status. Be prepared for a longer sales cycle due to the limited buyer pool, and don't mistake high asking prices for achievable sales figures.
