I came across 2 old Louisville slugger decal bats in fantastic shape.

One is The Good Night Baker decal. The decal is 99% intact, maybe 100%. The label on the bat matches to the time period with the line dash line. The bat utself is in perfect shape with nice lacquer and a clear bold brand. The person OI bought them from said they had been in a closet for many many years.

The other bat was a tris speaker decal bat from around the same time with the same marking. The decal is prob about 90% intact.

Is there any other method to determine authenticity? I can try and take pictures if that would help. Also, ANy idea of a value?
