Jeez ...

Just think, if the CCA had not proclaimed "Say NO to slabbing" (as still on masthead of this page,) you could obtain a definitive determination from an expert company that provides a guaranty of authenticity!

That determination reminds me of the lyrics to a 1950s doo-wopp hit song "dumb, dumb .. dum de little .. dumb ... dumb ... dumb" ... dumb ... dumb!".

Befitting here methinks.
