What is the value of a 1976 World Series baseball?

There is no way of telling the difference between a regular season baseball, and a World Series baseball from 1976. Rawlings started to make World Series baseballs in 1978 that features The World Series logo. If you have a signed baseball from the 1976 World Series then you would have to be more specific to who signed the ball. If you have a baseball that was used in the 1976 World Series without proper provenance that is was used in a Major League game or World Series it would be valued as a used baseball and have a low collectors value.
