Digits of Pi set

A while ago, someone (Coinosaurus, I think) asked me if I was going to do a "digits of pi" set after finishing my Prime Number Set. One could no doubt make a pretty cool set of 16th-20th century coins whose dates appear in the first however-many digits of pi. The first 500 decimal places will get you 26 coins from 1520 through 1971 (assuming I didn't miss any). Only three, 1609, 1861 and 1949 are also prime. Two dates, 1715 and 1536, overlap, sharing the 15. There are some good coin years in there for US collectors, including 1652 and 1793. Of course, I'm currently filling my 1652 slot with an English Commonwealth shilling.
While I'm not done with my Prime Number set, here's the Digits of Pi set so far. Happy Pi Day!

Try the link again. I had forgotten to publish the set.

I've always had a problem with the "Pi R Squared thing" statement. Don't get me wrong.
I always thought that "Pi R Round..........Cornbread R Squared".

Never talk to pi. He'll go on forever
Do we really need that many numbers for Pi?
If the circumference of the earth were calculated using π rounded to only the ninth decimal place, an error of no more than one quarter of an inch in 25,000 miles would result.

Thirty-nine decimal places of pi suffice for computing the circumference of a circle girding the known universe with an error no greater than the radius of a hydrogen atom

Just goes to show that it needs to be left to the imagination what additional digits are good for, like creating a set of coins to collect.

I'm quite amazed you can win Berkeley with only 450 digits.
One time I ate at a restaurant called "Pi" in Swindon, UK. They had all the digits on the menu. I memorized 30 digits in between bites without much effort.
