Its gonna be in the zinc penny signal neighborhood most likely...maybe he can tell you what position he was playing, what hand he was wearing it on, if he is right or left handed? If he's left handed, and was wearing the ring on his right hand, it would interfere with the glove...and vice versa, if he is right handed, and it was on his throwing arm, (right) think about trajectory, ...maybe he wasn't wearing a glove, and it was just a pick up game? Any info he can remember about the game or some unusual acrobatics that transpired? Questions like this MIGHT just narrow it down to a specific area for you. If its there you have a good chance of finding it, and possibly some others... I'm hoping he is lefty, and played right field, and the ring fell off between the dugout and the position as he removed his glove coming or going to that spot... Mud
