If you mean if these are from the Perth mint series with Gods, no. These are casual silver coins that were in circulation around 1930 in Greece. This one was something like the Peace Dollar equivalent for Greece.
I mean are they in a set series?
The latest , god knows how many Gods of Greek out there.
Now, Norse Gods series in 3 oz silver over $300 USD release price.
Don't worry, modern Greeks don't have an obsession with Olympian Gods ahahah... this was indeed on a series (5-10-20 drachma 1930), but only 2 of them had gods on it.
the 10 drachma featured Goddess Demetra (on silver 0.500): http://www.ebay.com/itm/like/191991223129? - I won't be featuring that one as it's below the threshold of my aesthetics...
the 20 drachma was Poseidon (on silver 0.500) - which is pictured in this post.

the 5 drachma didn't feature a god, but had the Phoenix (on nickel): https://steemit.com/photography/@alexgr/photography-greek-numismatics-pt1-phoenix-rising-from-its-ashes

Aside from these, from 1900+, you'll find Gods
a) in the 1912 - 20 lepta (Goddess athena): http://en.numista.com/catalogue/pieces2365.html
b) the 20 lepta / 50lepta / 1 drachma / 2 drachma set of 1926 with Goddess Athena: http://www.ebay.com/itm/Uncirculated-1926-Greece-Complete-Set-Drachmai-Lepta-Goddess-Athena-Head-/321395138495
c) the 1973 - 20 drachma with Goddess Athena: https://steemit.com/photography/@alexgr/photography-greek-numismatics-pt5-goddess-athena
...there might be a few more, in very limited quantities, proofs, collectibles, etc, like this: http://www.ebay.com/itm/GREECE-100-DRACHMAS-1978-SILVER-PROOF-50th-ANNIV-BANK-OF-GREECE-/390571863221?

...but generally, they are very few. And not always good looking. I mean the gold piece above on Zeus could be far, far better.
