New Era
1970
An "old" gold cap debuts in mid-season 1970 along with MLB's first double knits for the opening of Three Rivers Stadium. I read a story about the 1970 Pirates jerseys/caps awhile ago, how hard the team tried to find material for caps to match the “old gold” color in the new double knit jerseys. The coarse wool was what they came up with in 1970. But apparently it wasn’t popular, probably too hot, etc., so the switch to lighter wool (which had a lighter color) was made for 1971.
New Era
The first gold caps are of a coarse wool material.
1971-75
As discussed directly above, the switch to soft wool which has a lighter color gold.
New Era, KM Pro
1976
Pillbox caps are adopted by several clubs for the NL Centennial coinciding with the USA Bicentennial celebration (Cardinals, Giants, Mets, Phillies, Pirates, Reds, NL Umpires, NL All-stars). The Pirates keep this style for 10 years.
New Era
1976 - Only year of an "old" gold pillbox. Note that game worn Pirate pillbox caps will often have the size written on inside top mesh.
1977-79
Pirates switch from old gold to bright gold, introduce a black version, and undervisors turn grey. The team enters their “Bumblebee” period (‘77-84) where a dizzying array of jersey, pant, and cap styles allows for seven possible uniform combinations which the club varies on a nightly basis. Stargell stars appear on caps in 1978.
New Era
1980-82
Crown gets higher and ‘P’ gets slightly larger. From 1980 onward Stargell stars have black ‘S’ stitched in middle. Team issued caps from the 80’s are distinguished by the same heavy mesh lining from previous years. Replicas are lined with thin white foam.
New Era

‘P’ gets a slightly wider. Crown is maximum height. Gold caps switch to nylon.

New Era
In 1992, MLB logo is glued the on back at first, embroidered on by year end.
Raised emboidered logos begin in 1996.
COLLECTOR ALERT! This grey cap with gold P was intended to be the 1997 alternate. But when the season rolled around the alternate cap had a black P. I've heard two stories about it: the Pirates decided to change the logo to black after the gold P caps were made; or, the gold P caps were a New Era mistake. Either way, the caps were dumped by retailers, never worn on-field, and depending on your point of view they are a collector's item or a mistake.
1997 Prototype NOT WORN ON FIELD
New Era
1997-2000
Jerseys are redesigned changing the font on the home, the road gets pinstripes, and an alternate black jersey with red trim returns red to the colorway for the first time since 1946. Two new caps debut: a road grey cap with an outlined ‘P’, and an alternate cap with a red bill.
New Era
The grey cap is rarely used after 1998 (black caps are worn home & away). The red bill alternate cap is gone after 2000.
2001-05
New Era
A new alternate cap is introduced, inspired by the style worn in the Turn Ahead The Clock game in 1999 (note - it's not the same as the TATC cap on which the red undervisor wrapped around the edge to the top of the visor). Worn with the black alternate jersey, it's the only MLB cap with a red undervisor.
Alternate yellow bill/red undervisor cap retired after 2005.
