Approximate value for Vintage Sun Coliseum 300?

[schroecr]

I'm looking to sell a 1971 Sun Coliseum 300 bass head, but I have no idea what to even ask for it. I have several interested buyers in my area as it is in great shape and sounds amazing, but I don't even know roughly what its worth. I've searched ebay to find similar sales but no dice. Can someone help give me some good honest feedback. Thanks.

As with a used anything, it's worth what somebody will pay for it. Opinions (unless given by someone with a checkbook in hand) are useless, and have absolutely zero cash value.
You can dictate a price as the seller, and will or won't sell, or someone can offer you a price which you can in turn accept or reject. But, advice from someone without "skin in the game" does you no good whatsoever.

Actual market research is another story altogether. while I find eBay an erratic, and usually inflated barometer of vintage gear ACV (actual cash value), at least these are real people spending real money rather than some self proclaimed experts' "opinion"

Follow it and see what it brings, then you will know what it's worth to somebody.
Of course, this may be your amp.

First you have to know what you got. In 1971 there was a Coliseum Bass but IIRC, the Coliseum 300 wasn't made until the 80's. What does it look like? Any rust?
