Undeveloped it has little to no value in my opinion. It has never been developed so will have no human traffic, is a search term that virtually nobody uses, and is very niche for a product that would be part of a bigger grouping. Also as google doesn't pay any attention to the keywords in a domain itself it has no inherent search engine bonus value.
Well there doesn't appear to be a public record. However if this domain sold for that it was supposedly 11 years ago and someone massively overpaid for it, because from then nothing was done and it had a parked page on it. Eventually it expired and you picked it up a few months ago, I assume for registration fee? Does this really sound like the activity of a 'valuable' $6k domain? If nobody wanted it for a few dollars, it was never used to make money, and it didn't get sold from person to person, I can't see how you can ascribe a value of at least $1000. However as biggie said you could put up a site for amazon affiliate bath towels or something similar - how much human traffic does it get? Alternatively you can try putting it in the 'make offers' section here. If it is worth $6k you should very quickly be inundated with some offers.
