One more clue I found. I have yet seen a worn 'FG' on the 006 reverse on a 1988 coin. They were added to fill in the rest of that year. So they usually have little wear on those initials on the 1988 reverses. So when I see a little die wear on that device, it has always been a 005. But location and the top of the 'G' is the real clue here on this one.
