How To Make Your Own Homemade Geocoins ...
There's a cheaper way to do it. Jonathan and Lindy found a way to create your own, low-cost, custom wooden nickels for geocaching. Thanks!
For instructions go to Jonathan Swatkowski's blog at

My solution to, "...they might still smear a little if they get wet." Maybe try spraying them with clear interior/exterior sealer enamel, like Valspar clear satin.
