Fatbat: Sorry to say but you're almost completely wrong!
16-20 months of revenue? Most people I know talk at least 3 years. I don't put very much weight on parking revenues to determine the value of a domain though. A few cents a click is hardly justification for valuation.
For resellers and traffic buyers this is a normal price assuming non-english traffic (especially for polish one I am sooo sure). Would be nice to get more but it does not happen in 99%, lets say. Don't think about this name as about english one only because it is dot com!
The Polish design studio is a good candidate for typos, but as pointed out, pretty obscure. The job thing as well.
If you search "polkadot" in Google those sites aren't even in the first 4 or 5 pages of results (I didn't look further). There's a bunch of other design sites, PR firms, crafts sites, etc. that could be the target for type in traffic.
Please understand that this is not a typo - just other .ext.
In Google
polkadot.pl (service devoted to polish women working in UK) is the FIRST one for over 10 millions of results, always if you type polkadot, polka dot or "polka dot" - over 8 millions results. I use normal connection and a proxy one so Google dont determine my location (so I can use google.com instead of google.pl).
Please check up again! You're definitely not right.
I think targeting Polish "jobs" on Sedo is bad advice. You could be opening yourself up to a clear udrp case with that company.
I'd say this could go to any one of the many "polkadot" companies out there but in the meantime you need to be careful in developing it that you wouldn't step on anyone's toes that already has a established "polkadot" business willing to drop down for a WIPO case.
If he wants to park this kind of name with some profit, keywords related to job etc. (mostly in polish) are the only solution. I know it after having bunch of polish job names. And you know how big is job emigration from Poland to UK? It is huuuuuge, unfortunately. This is why this name has decent revenue and CTR (I suppose but Varchar can correct me).
I can say that THE PATENT OFFICE OF THE REPUBLIC OF POLAND has not registered any TM concerning neither polkadot, nor polka dot nor polkadot.pl, polkadot.com. This is what I've checked up in their database although there can be still some TM issue (according to my experience: less than 1%

I'd say 10-20k is a fair price if you can find a buyer.
Can you tell us what's your experience with this type of european names. Have you ever sold one even? Your price can be acceptable for really craaaaazy end user but is far from reality. Although I am honestly wishing Varchar will sell it for even more!!!!!
