Robin, like Derek Jeter, almost exclusively swung LVS P72's throughout his entire career. Yount did swing a K55 model during the '70's before settling on an unfinished 35" 32oz P72 with a cupped end. Cal Ripken Jr. was another player who swung a tremendous amount of LVS P72's throughout his career. Yount's gamers have a very similar look throughout his career, they should almost always have his number "19" written in bold black Sharpie on the knob. This was written by the Brewers equipment manager. Yount used varying degrees of pine tar throughout his career, sometimes light, sometimes heavy. The amount of tar typically coincided with the amount of game use. His pine tar would have an inconsistent patter right above his hands, this was due to Robin grabbing the tar with his bottom hand and transferring the tar back down to the lower handle. Yount hit with the label up, game use should be on the left barrel. His well used gamers will show a donut ring around the barrel and will also have marks on the right and back barrel from tapping his bat against the side of his cleats. Often times, the blue shoe polish would transfer to the bat. Yount's bats, though seemingly boring at times, can actually carry quite a bit of character. One interesting note on Yount, he would typically swing his bats with wider grain in games and save the narrow grain bats for batting practice. When buying a Yount, look for all of the characteristics above along with the wider grain, cracked examples.
