Intel C3104 16-bit (4 x 4) Content Addressable Static RAM, Very Rare Version

This Item is a Very Rare Version of the Intel C3104 16-bit (4 x 4) Content Addressable Static RAM,  in White Ceramic with Gold Plated Pins, still in its unopened original container as per the Photos. 

The Date Code on the Chip indicates that it was manufactured during in week 39 of 1973 most likely in the USA.

The Intel 3104 is a high speed 16-bit Content Addressable Memory (CAM). 
It is a linear select 4 word by 4-bit array, which is designed to compare data on its inputs with data already stored in its memory and to indicate a match when these data are identical. 
This equality search is performed on all bits in parallel. 
The 3104 can also be used as a read/write RAM with linear selection addressing

I can assure any buyers that the prices for these vintage Chips will rise significantly over the coming years as they have done so over the past 30 years so it will be a good investment for them as the majority of the older chips have been scrapped for their gold content.
