Median asking price across 32 live sealed listings. Sellers' asking prices, not confirmed sales — treat it as a ceiling.

What it actually sold for
Sellers are asking 22% more than buyers actually paid. The $25 figure above is a ceiling; this is the floor to negotiate toward.
Completed BrickLink transactions over the last six months. Real sales, not asking prices.
Should you buy it?
Still trading near its $20 retail price. Retirement alone hasn't moved it.
Pay no more than $3

▲ 25% above its $19.99 retail price
How to read this. The value is the median of live sealed listings, after removing instructions, empty boxes, used sets, multi-set lots and implausible outliers. Real sale prices usually land below asking, so the buy-below figure is deliberately the conservative end of the range.
