There's no question that the upcoming presidential inauguration is historically significant.
"It's just monumental that Obama came in to office," acknowledges Misha Green.
But there are many questions about what commemoratives will become valuable in years to come. And many of those questions concern the Barack Obama inaugural dollar.
"There's really very little value to them," says Better Business Bureau's Dick Eppstein.
However, that isn't stopping people from buying the coins. And they're easy to get because they're advertised on TV and various internet sites.
But here's what you need to know: They're not legal tender. Eppstein says as long as you're spending the $10 to $20 for the commemorative value, that's fine.
If you're looking to turn these coins into change, however, think again.
"I would suggest caution," Eppstein said.
