DollarDots.com - brandable, nice name for a informational site fully around the dollar. Not sure if you find enough buyer for a quick flip, with work and time I'd say 400-800$.
HisDollar.com - GoValue similar sales are interesting. Could be shop for men to spend their dollar, well brandable too I'd say. With quick work, maybe a quick sale around 600-1000$+.
BetMoneyOn.com - hard to say, can one bet somehow on .com domains? Idk. It's memorable anyway, thinking of the name like "Bet money on .com-websites" one could develope a info site about betting sites. Well researched and with the best intentions in mind, I could see a profitable site. Probably better to ask someone you know if interested to do that or do yourself.
Another meaning - "Bet money on commerce".
VivaRome.com - A quick sell to some rome tourist stuff site or whatever, why not... definitely good brandable, I like the Englitaly here, especially for companies that have to do with tourists.
