Are you sure it's the same inlay -- saying both "Nassau" and "Bahamas?" If so, then we need to know if a similar $1 inlay (NASSAU) is on the other denominations of that series. I missed a whole series (short-lived): Between Trump to Merv. We do know of the 1492-1992 Merv Chipco just after the takeover, but very little more.
