I finally found a couple of catalogs in my collection from that era. A 1990 Helix (of Chicago) catalog has a new 500CM chrome with 80mm f2.8 CF and A12 magazine for $1995. The description says it includes waist level finder, and rapid wind crank. Extra A12 backs were $479. A couple of the popular lenses - 50mm CF was $1628, and 150mm CF was $1759, both T*. I don't know if those prices are Hasselblad list prices, but I suspect they may be. I don't know if the New York discount dealers such as Olden sold Hass much below list price or not.
In a 1991 Adorama catalog the "500 Classic Kit" consisting of 500CM chrome body, 80mm CF and A12 was $2295, and $572 for an extra A12 back. 50mm Distagon FLE CF was $2168, and the 150mm Sonnar was $2126. I don't know how often Hasselblad increased prices over the years, but I seem to remember a noticeable price jump back about then.
The May 1963 "Popular Photography" magazine has a Hasselblad ad giving a price for 500C with 80mm lens of $549.50. When I finally bought my first Hasselblad, a used 500C with chrome 80mm and 12 back at a camera swap meet sometime in the 1980s I think I paid $600 or $650. It wasn't until many years later when digital really killed Hasselblad values that I bought my 50mm and 150mm lenses. I don't watch complete 500Cs on eBay really closely, but I think they may be selling in the $450 price range.
