What year is this Bear Super Grizzly?

[portugeejn]

Anyone know when this bow was made?  Bear Super Grizzly with Fascor.  The string that came with it is a red endless loop with green serving.  I made the flemish string for it, although the string that came with it is in really great shape, I thought it better to put away and shoot a new one.  

I know 1970's sometime before 1978 and have read the coin was changed and not flush at the end of '72.  Thanks.

I think they are 1973 to 1976. There were different color super grizzlies, blue futurewood and green futurewood. I've got a black one like yours only lefty.
