Forecasts are directional estimates, not guaranteed future prices or investment advice. Actual value depends on condition, demand, fees, and sale timing.

Released in 2000 and long retired, King Leo's Castle (set 6091) is a US-numbered Knights Kingdom I variant whose named characters and raised baseplate create distinctive collector interest, and its regional scarcity has supported strong post-retirement demand, while periodic Castle revivals add some volatility.
