various chips fluctuates as new chip "discoveries" (such as yours) are uncovered. The $1 chip price probably would remain around the same, but the 10 cent & $5 chips may reflect a lesser price due to the number of chips that you have found. As Andy said, you would most likely realize better pricing if you sold the chips individually versus as an entire set. Selling the set as a whole would severely limit the persons willing and/or able to afford to buy them all...and THAT person would most likely then sell them individually!!
Good luck & let me know if you do decide to sell them individually as I would be interested in a ten center.
