I have about 30 of them collected in the last 30+ years. Mostly of places we've been or given as a gift, My favorites ones are my pewter ones from Alaska, Washington DC and the World of Coke Cola in Georgia. All 3 places are ones that I picked up while attending meetings or visiting my son and family in Alaska. I am always watching for them. All are of states with the exception of the Coke cola one, and I even have one from Mexico, London, these two were from friends that were on trips there.
In February we are going on a cruise for our Anniversary. So I will get several more then.
