what are these valve covers worth.

[54 jimmy]

i bought these valve covers a while ago for my 305 motor with plans on finding an intake with a dickie tube. as the best laid plans go i didn't find a intake within my price range. my fiancee was already not to happy that i bought the valve covers for $125.00 but they are orignal 283 chrome script covers and the were in great shape for how old they are. their are a few dents in the top of them from my 1 year old daughter taking the and playing the drums on them. i can blame her for the dents though i left them out where she could get at them. any hoo i got a holly intake for free but no dickie tube. i still have my orignal covers so i am going to clean the up and use them. so what are these worth. can i at least get $100.00 for them or am i asking too much.
