What is a Invicta Mastermind Game worth?

What it sells for

Half the Invicta Mastermind Game sales in this set closed above $15.92 and half below it. The middle of the range runs $13.21 to $20.24: that band is the number to price against, not the single highest sale you can find. Meanwhile 21 people are currently asking a median of $14.95 for one, $0.97 below what they have been going for. Asking below the sold median usually means sellers are undercutting each other to move stock, so don't read it as the ceiling. More on that gap.

What condition these sales were in

Every sale we have for this item is pre-owned, so the median above describes pre-owned examples and nothing else. We have no data on what a different condition fetches, and would rather say so than guess.

What moves the price up or down

• The spread is wide. The priciest sale here ($29.99) went for 2.9× the cheapest ($10.20). A gap that size is rarely the market being irrational, it is usually condition, completeness, or what came in the box.
• Where you sell it matters. These comps come from eBay. The same item moves at different prices, and different speeds, depending on the audience, and a local sale trades some of the price for not shipping it.
• Recency. These 8 sales closed between Jul 29, 2026 and Oct 3, 2026.

The sales behind this number

Every row is a real completed sale on a public marketplace. The links go to the original listings, which the marketplace may eventually remove.

How current is this?

We collected these comps on Oct 20, 2026 (19 days ago), and the most recent sale in the set closed on Oct 3, 2026. We do not re-fetch prices every time someone opens this page: refreshing costs real money at every marketplace, so these pages are rebuilt on a schedule rather than on demand. Treat a set older than about three months as a starting point, not an appraisal.
