Condition: As with all collectibles, the condition of the coin set plays a significant role in determining its value. A set in pristine, uncirculated condition will command a higher price compared to one that shows signs of wear or damage.
Rarity: The mintage number and availability of the coin set contribute to its rarity. Smaller mintage numbers indicate a more limited supply, making the set more valuable.
Based on these factors, the estimated value of the Las Vegas Hilton Spacequest Casino Star Trek Experience silver five coin set can range between $300 to $500. However, it's important to consult with reputable coin dealers or experts to obtain a more accurate appraisal based on the specific condition and other market conditions at the time of evaluation.
