Show me Pi today

Today is special to folks who like to math and sweets - Pi Day. Post how you celebrate Pi day.

I thought I'd show my coins with Pi and others could show theirs. Turns out a Roman Republican coin collector (me) has few words with Greek letters. The only one I found is a tongue in cheek Pi -


I show the card from Ken D because I can not see a Pi on my coin. Evidently some of these have a Pi.
Pamphylia, Aspendos, 465 - 430 BC, Silver Stater
Obverse: Hoplite warrior advancing right holding spear and round shield. The end of the spear behind the soldier has some extra lines, like a trident pointing the wrong way. I do not see them on other examples. The lines could be an insect with 6 legs or flow lines on the die.
Reverse: Triskeles, 3 legs running, below - lion crouching left in background, above - EΣT, all within incuse square.
10.73 grams
19.4 X 17.3 X 4.8 mm

I thought of Pi while looking at this coin on acsearch -

Great thread idea and coin!
This pie has a hole in it! It even has the flaky crust around the outside. And the triskeles are running to have a slice:

 

Ahhh Pi day... so many happy memories.

The ultimate pi day happened on March 14th 1592. Sad I missed it.

I hate math but I love sweets, esp. Raspberry Torte. No coins though....

 

Interesting coincidence...or not...but we just had a damaged mint mark on a Buffalo 5c posted today that looked more like the pie (pi) symbol than anything of D or S.

 

Next time don't wait so long to the penny...you can always "round" up to pie/pi (pie r round) for a slightly smaller check in the range of $20-$25 or so. Many younger folks today aren't going to know the symbol or its numerical equivalent, anyway.

Okay I cheated... I actually had no idea my ptolemy X had pi until this thread.

 

..actually, my Nero dupondius isn't showing Pi, rather that mark is showing its worth 2 As's...and i hope you don't think i'm one for showing it as such

 

Still purdy cool symbol, though. Bar above II.

 

thanks friend...yeah it is kool....i gotta tip my hat to @dougsmit for the education on this lil jewel..

 

For Cleopatra, Π = 80 drachmas.
