How much of a difference does a cellar vs basement make on the appraisal?

For example a house has 2 floors and a basement, each level is 600 sf, the county records will show that the house is 1,800 sf.

A house with 2 floors and a cellar, each level is 600 sf, the county records will show that the house is 1,200 sf. 

Technically the houses are the same size but the cellar just doesn't count towards the square footage. Does this make a huge difference in value when the house is appraised? 

Thank you in advance.
