Pat,
If it is an iconic scoop such as Trump on his knees being knighted or knifed by the Queen of England then it's worth $40,000 or multiples of that!
Otherwise regular for news stories be thankful if you are offered $200 to $5,000 according to the excitement it would bring.
Of course, if I could get away with calling myself Annie Lebowitz I would always get top dollar, if they wanted my pictures!
