I still have some catalogs from when I was a kid, which allows me to present to you a look at the retail authentic NBA jersey market in the years 1990-1995. I'm sorry some of the scans aren't perfect, as I took these to school, read them as I went to sleep, and ate my breakfast cereal flippng through the pages.

Authentics Price: $69.95 - Size 36, 38, 40, 42, 44, 46 ; $79.95 - Size 48 & 50
Replica Price: $24.95 - Size S, M, L, XL
Notes: Last year of Sand Knit NBA jerseys, and a pretty limited selection...

Authentics Price: $74.95 - Bulls & Pistons ; $109.95 - Celtics, Knicks, Lakers, Spurs
Replica Price: $32.95 - Size 36, 40, 44, 48
Notes: The guy wearing the Bulls jersey I believe is more representative of what you would get if you ordered an authentic in 1991/1992 than the one that is laid flat, with the thicker white letter/number trim, and the NBA logo up super high on the strap.

Authentics Price: $89.95 - Pistons; $109.95 - Lakers; $119.95 - Bulls, Celtics, Knicks, Spurs, Warriors
Replica Price: $39.95 - Size 36, 40, 44, 48
Notes: Interesting to see the screened 1991/1992 Bulls jersey was being closed out at $74.95!

Authentics Price: $79.99 - Sonics & Pistons; $129.99 - Bulls, Heat, Jazz, Knicks, Lakers, Spurs, Warriors; $139.99 - Hornets, Magic, Suns
Replica Price: $39.99 - Size 36, 40, 44, 48, $34.99 - Size 8, 12, 16, 20
Notes: Again the NBA logo is up high on the strap, this time you see what a Spurs version would look like. I don't know for sure what year the NBA logo started being more properly placed, but don't judge based on these scans. They had been recycling that Spurs jersey picture all the way to the 1993/1994 catalog, but I think the picture was taken in 1991/1992, and I don't think the NBA logo was still being placed up that high anymore. Also interesting that the Spurs jersey is a 40, but you can only purchase a 44 or 48...

Authentics Price: $129.99 - Jazz, Pistons, Rockets, Sonics; $169.99 - Magic; $199.99 - Bulls, Heat, Knicks, Lakers, Warriors; $239.99 Hornets, Spurs, Suns; $259.99 - Blazers
Replica Price: $37.99 - Size 36, 40, 44, 48, $34.99 - Size 8, 12, 16, 20
Notes: Shorts now for sale too for $119.99.

Authentics Price: Unavailable
Replica Price: $39.99 for adult sizes, $34.99 for kids sizes (Dream Team 1994 only)
Notes: Both Dream Team 1 and the 1994 edition never seemed to have authentics for sale, just replicas, so have extra caution with jerseys deemed to be from the era and "authentic with sewn letters and numbers". The first release of Dream Team 1 jerseys did not include late additions Clyde Drexler and Cristian Laettner, so I would say those two players would be harder to find than the other ten...
