5 Classic Games You Might Not Know Are Worth Tons of Cash

The boxing game James Buster Douglas Knockout Boxing was created to take advantage of James “Buster” Douglas’s surprising win over Mike Tyson in 1990. Originally released in Japan as Final Blow, it was renamed for its release in the U.S. and other regions to highlight the famous match. Most versions of the game aren’t valuable, but the Sega Master System edition is extremely rare. This is because it was released late in the Master System’s lifespan, with only a small number of copies produced. Current estimates from Price Charting show a loose copy selling for around $336, while professionally graded copies can fetch prices exceeding $7,240.
