Faultless, I think, made balls with Trevino's name on them back in the 1970s.
While that might sound like a long time ago, and you think you might have something rare, they made millions of them - so unless it's in pristene/like new condition, it's not worth much.
Can you authenticate it ? It has value only to a Trevino fan . Might be worth $15 or $ 20
