MEARS Auth, LLC’s Comments and Working Notes for:
1960 Bill Mazeroski Pittsburgh Pirates Road World Series Uniform 

Size: The jersey is tagged as and measures as a size 44. This was confirmed both through measurement across the chest and comparing it with period on hand MacGregor vest products in sizes 40, 42, 44, and 46. This is also consistent with two recently evaluated 1960 Bill Mazeroski Pirates home jerseys (Rawlings products). The 1960 Pirates version of the World Series Program lists Mazeroski at 5’, 11”; 182lbs. As such I would consider this to be an appropriate sized jersey for Bill Mazeroski at this point in his career. The jersey is accompanied by a matching pair of pants. The tagged size is a 34” waist and 25” inseam. These are also both actual measurements and are also assessed as being appropriately sized as well. (PLATE I) 

Manufacturers Tagging: The jersey features a c.1958-1961 style MacGregor tag (blue version that transitioned to green in 1961). Supplemental tagging for the year and set appears on a single flag tag in the lower inner front tail. This too is assessed as being appropriate when compared to an on-hand 1960 Pittsburgh Pirates road jersey in my exemplar library (Bill Burwell; Coach). As such, I would offer that this is an appropriately tagged jersey and pants. (PLATE II) 

Construction/Style: The jersey is constructed of a professional grade wool blend fabric that is consistent by weave with on-hand professional grade MacGregor major league uniforms. The jersey compares favorably without exception to the above mentioned on-hand 1960 Pirates road jersey (MacGregor product) in my exemplar library. While Rawlings provided the home uniforms for the 1960 Pirates (to include the World Series), the road uniforms were provided by MacGregor. Two characteristics worth noting are the unique MacGegor buttons (convex, two hole style) and the alpha-numeric fonts. Both of these can be seen in the road uniforms worn by the Pirates in Yankee Stadium during the 1960 World Series. (PLATES III-VII) 

Use/Wear: The jersey shows evidence of light use and wear. The same can be said of the pants. 

Event Specific Attribution: The uniform was sourced from the personal collection of Bill Mazeroski as lot # 213 in Hunt’s Fall 2013 Auction. According to Mr. Mazeroski, this was said to have been his 1960 road World Series uniform that was removed from his locker following the 1960 World Series. This same auction also featured his 1960 home jersey and other artifacts he retained from the 1960 World Series. Given the provenance, the light use, and the photographic evidence that confirms the use of MacGregor road uniforms at Yankee Stadium for the 1960 World Series, I have no reason to question that it is in fact Bill Mazeroski’s 1960 World Series uniform. Had this been a regular season offering, I would have expected much more use and wear given Mazeroski played in 151 games that year. 

Opinion: In my opinion this jersey possesses all the characteristics you would expect to see in a jersey manufactured in 1960 by MacGregor for use and wear by Bill Mazeroski of the Pittsburgh Pirates during the 1960 World Series at Yankee Stadium. All lettering, numbering and supplemental tagging is assessed as being original to the garment. The MEARS worksheet and grading criteria provides for 5 categories for which points may deducted. I found no reasons to deduct points. 

As such, the final grade for this jersey bearing hologram #313246 is A10 

NOTE: No points were deducted for light use since this is just what I would and should have expected to have found in a uniform worn for a maximum of three games (Games 3-5 at Yankee Stadium).
