You would really be impressed with the values of the Las Vegas Chips - the $5 lists for $50-$60 and the $25 lists for $175-$199. Even though the $1 is not listed it would be high as well. There have been several cases where chips made for one place were later used at another. It might be worth you time to try and find out if the Matty chips were used in Las Vegas. Perhaps there is some relationship between the owner of Matty's Tropics, located at 3337 Las Vegas Blvd in 1955 and Matty's Bar in Stockton - though I can not imagine moving from Las Vegas to Stockton. But then, in 1955 some not so nice folks still had a lot of influence in LV...
