Market Valuation & Pricing Notes
Raw/ungraded examples in original Royal Mint box with COA typically realise £2,500–£4,250 on UK dealer sites (Chards, Atkinsons, London Coin Company). Graded PR69/PR70 examples command significant premiums; NGC PF69 listed at £6,891 (BullionByPost). The gold proof is distinct from the gold piedfort (31.10 g, mintage 40). No circulation wear exists for this issue; 'circulated' in schema context equates to raw ungraded proof condition.

Common Fakes & Variant Confusion
Most common confusion is with the 2009 Kew Gardens silver proof (mintage ~3,500, 15.5 g but .925 silver) or the gold piedfort (31.10 g, mintage 40). Counterfeit gold proofs exist – typically cast copies with porous surfaces, incorrect weight (often 14–16 g but wrong SG), soft edge, and blurred pagoda roof tiers. Always verify weight, specific gravity, and proof finish. The plain edge distinguishes it from circulating cupro-nickel (milled) and silver piedfort (milled).

Immediate payment, lower friction; buy prices typically 10–15% below retail list; no buyer premium
