Does H mean Heraea/Heraia?

BCD Peloponnesos 1369.1 var

Does the letter H to the left of Artemis' head on the reverse stand for Heraea/Heraia?  (Is not visible on my coin.)

I do not see any H, which in any event is the Greek long E.  In Greek the sound H is unexpressed except at the beginning of a word in a text where it is indicated by '.

H is one of many forms of the abbreviated ethnic of the city. It is found prominently displayed on many (but not all) of the coins of the city. On other coins the ethnic is the letter E in accord with djmacdo's note on how the ancient Greek word "Heraia" was pronounced. I find the display on the reverse of the third coin below most interesting ...a small H followed by a BIG E  to right of which can be discerned a small A and small I... I think it reflects the difference in pronunciation versus the spelling. The fourth coin takes thus a step further emphasizing the E in the pronunciation. Finally to add to your confusion on some coins of Heraia the ethnic is abbreviated to EP (fifth coin below). So we have H, HE, E and EP all read as an abbreviation of Heraia.

In Archaic Greek, one has a consonantal 'H'.  This in the Classical era becomes the vowel long e.  Of course, the division between the Archaic period, and the Classical (or Hellenic) period is not hard and fast.  Some cities use Archaic letters long after the Archaic period.  The  of Corinth for example, or the  of Elis.

Thank you all for the information and explanation. 
It's the coin details like this that I enjoy (almost as much as owning the coin).
