ebay

The most expensive items on eBay from Idaho will easily cost you more than $20,000 per item.

How much would you be willing to pay for a Boise State championship ring from the 2017 season?

The rarest of all Idaho plates are from the years 1928, 1947, and 1948.

I absolutely love this map that eBay put together.  They went thru all of their data to find which products were bought most and in which states.
