The resale value of an arcade machine is determined by several crucial factors that collectors and enthusiasts carefully evaluate. First and foremost is the machine's physical condition. Cabinets with minimal wear, original artwork, and functioning components command significantly higher prices than those with significant damage or non-original parts. The rarity of the game title plays a substantial role, with limited-production games or cult classics often fetching premium prices in the collector's market.

Authenticity and originality are paramount to serious collectors. Machines that retain their original monitors, control panels, and internal components are vastly more desirable than those with modern replacements or modifications. The provenance or history of a machine can also add value, particularly if it has an interesting background or previous ownership.

Market demand fluctuates based on nostalgia trends and collector interests, with certain eras or genres experiencing periodic surges in popularity. The quality of any restoration work performed is critical; professional, historically accurate restorations can enhance value, while poor modifications can substantially diminish it. Additional factors include the machine's operational status, with fully functional units naturally commanding higher prices, and regional market variations that can affect availability and pricing in different areas.

Finally, the completeness of the machine - including side art, marquees, and original documentation - contributes significantly to its overall valuation. Understanding these factors helps both buyers and sellers navigate the complex arcade machine market effectively.
