Comment: Serial numbers are stapled on a paper tab to the left of the coin box inside compartment bottom as well as an identical stapled paper serial number on the left upper side inside the back of the top box. There is an additional number 1586 stamped on the right near corner wood area of the playfield as you stand to play. It appears unique to the playfield and don't believe it to be the serial for the overall game. This game is a pitch and bat created by United Manufacturing Company of Chicago, IL. It possesses three metal unpainted ramps directing ball to the home run upper deck and fast and slow pitch buttons. It also possesses an upright bat like lever to engage the batting feature. This March, 1959 game should not be mistaken for the United's Deluxe, 1960 game which is identical but sported a match and free game feature that does not exist on the Yankee, 1959 version.

Nudge History:
help

Nudging allows IPSND members to adjust the SerialBot score for a submission with a photo attached by determining of the photo clearly shows the existence of the serial number submitted. However, nudging is only 'Open' until there is a clear determiniation of accuracy by members. If a serial number has more than 5 nudges and the total of those nudges is greater than 4 or less than -3, then the nudge will be closed automatically after the last nudge. If a submission is controversial and there are nudges in both the positive and negative direction, then the nudge will remain open until the balance of voting swings the point value beyond 3 (positive or negative).
