I will watch traffic for a few and then decide how to proceed. I have parked them at Sedo.
This one is really a gamble. idn.idn is suggesting that in the future they may no longer support common punctuations but its up in the air. For now they remain as being seen only as 1 - 0 dot com in the search engine.
If they decide to keep things as current then these domains may have a very high value in terms of seo development.
I will go with what the current ads that are being pulled in to the domain with the keywords of 0 1 2 3 4 5 6 7 8 9 and 0 ie 0 pulls in 0 intrest credit cards, all are pulling in some high cpc ads.
