Devin Night has made his first 20 token packs free. Search for "Devin Night" on Roll20, and you will find a variety there. These free tokens are his earlier works, and are not quite correctly scaled (visually) for what you might expect. For example, goblins look the same size as Medium creatures. The packs do include things like some animals, camp scenes, bodies, as well as characters and a few townsfolk (not enough to give everyone in Sandpoint a unique token, though).
On his site, he has a couple of free token packs with Pathfinder characters. These were made on commission for paying customers who have agreed to make them available to the public. Gogmurt, Koruvus, Ameiko, Shalelu, and more are there.
His kickstarter included a good number of basic monsters.
Many of the other packs are probably available through Roll20's marketplace. I prefer to buy direct from Devin Night's site, so I can use them in multiple places.
You could also choose to pick up some of the Pathfidner Paper Minis here on Paizo's site. There is a Sandpoint townsfolk set in addition to the sets for each part of the AP. You could extract the images and with a little cropping make full-face tokens out of them for your own use.
