This is a dog tax rabies vaccination pet license token tag no date from San Mateo County California. It's brass, 29mm in diameter. Please take a look at the scanned images. This would make a nice gift, or addition to any collection.
Please take a look at my other token and medal listings. I combine shipping on multiple items. Please commit to buying, then request an invoice or combined shipping, and wait for the invoice to come back to you before paying.
