The "X" is throwing me off a little bit, but if the only numbers present are 94392 I would have to guess sometime between 1923 and 1940 b/c the sweet 16s were #ed 1-126,175 within this range. Value depends completely on Grade (there were 4 different grade models 1-4, each got a little more detailed as they progressed with more checkering and inlays), if it had a solid or vent rib, and obviously condition. The value ranges from a Grade 1, no rib, 60% at $250, to a Grade 4 vent rib 100% @ $4,900. Hope this was helpful!
