The Auto/Truck Plaza chip isn't the easiest chip to find, and the Silver Bird chip has the "questionable" error of IAS instead of LAS.

If you're one of the newest members into the chip collecting hobby, a search of EBay will show you the only $1 Auto/Truck Plaza chip for sale is this one. Here's your chance to get a good, solid Auto/Truck Plaza chip for your collection.

And if you collect variations, this could be a one you need. Some people believe this is an error, with the LAS in LAS VEGAS looking more like an IAS. Some believe a little bit of use caused the L to turn into an I, thus not an error but a used chip. I will leave the decision to you.

If you are interested in either chip, follow the link below. Good luck.
