That's very nice! And, you deserve it, so even better!
When I passed the PE I didn't get a raise, and my boss (a very non-engineer type) even told me "I doubt that having that certification (aka PE) really makes any difference, or will cause anyone to increase their respect for you." He did announce it in a manager's meeting the next week, though, but everyone already knew.
But a few weeks later, our "state" legislature gave me a Resolution, honoring me for being the "first" licensed environmental engineer out here. That was kind of cool.
