Thank you for a very fast response! Is there any particular introductory level book (I dunno... like a "Small Biz For Dummies"? or something along those lines) you'd recommend?
The reason I thought it might not be taxable was that I thought it might fall under being called a hobby or something. Maybe a purely layman's misconception? ALSO: $3,000 or so of the antiques were inherited from my mother and her estate was not large enough for me to owe taxes on it. Wouldn't their sales be excluded?
I think the above will cover my question completely!
Final Question (promise!): you didn't address the aspect of selling the inherited items? They're not recorded officially anywhere, so I have no way of PROVING that I got them from my mom, but as noted, we're not talking about the Cartier diamonds here. :)
