Is my old Sigma SLr lens 'for pentax' 75-250mm worth anything?

[abstraction]

I have an old sigma lens from my predigital days.

It says: Sigma Zoom (& a green symbol I can't read) 1:4~5 f=75~250mm. Multi coated E-911656. Made in Japan. For Pentax-K. It also has an achromatic macro lens attachment.

I'm not trying to sell it here. Just interested to know if it's useful, should i sell it on ebay (to contribute to my new canon) and about how much it might be worth?

Given that information, how should i describe it if i put it up on ebay?

Hi Abstraction. Can't modern Pentax DSLRs take K-mount lenses? I know that the latest ones take KAF mounts, but isn't that just autofocus?

I did a search on the net and found a couple in the USA that sold for USD$65.00 and USD$69.00, so considering the value of the AUD, you might get $60.00 AUD.
