Well, doubling your penny could be expressed as 2d where d equals the amount of days you have been doubling. So a year would be 2365 or 7.51533626 X 10109 (109 zeroes). This equates to $751,533,626,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,

000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.00

I'm pretty sure that's more than a Google. BUT WAIT: THERE'S MORE!

If you keep the money from each day, you would need to turn this into a permutation. This means its 2365 X 2264 X 2363X 2362... all the way to 21. This is way too much money and I don't even think there is a name for this number.
