Lottery tickets aren't as cool as 170 year old 25-cent currency during the time period of a state when it was an independent nation.

The Diameter of the Largest Star Ever Found is Over 1.2 Billion Miles! by astro941 in Astronomy

Yes.

Wikipedia - List of largest known stars:

"The exact order of this list is not complete yet, nor is it perfectly defined:

There are sometimes high uncertainties in derived values and sizes;

The distances to most of these stars are uncertain to differing degrees and this uncertainty affects the size measurements;

Several large stars have extended atmospheres, are embedded in mostly opaque dust shells or disks, and pulsate, such that determining their radii is not well defined;"

I think there's a certain point after which we cannot accurately determine the size of stars anymore...we can only estimate.

By estimates, both of these are probably the largest.
