Here's another coin unknown to me, a bunch of grapes and letters T A and on the other side of the image of women.What could it be for the coin?
Greek. Temnos, in Aeolis (also spelled Aiolis). The "woman" on the obverse is Dionysos. Like this one from CNG: http://cngcoins.com/Coin.aspx?CoinID=229848
AEOLIS, Temnos. 3rd-2nd centuries BC. Æ (12mm, 2.12 g, 12h). Wreathed head of Dionysos right / Grape bunch on vine; flower to left. SNG von Aulock 1673 var. (monogram to right); SNG Copenhagen 251-3 var. (no flower). VF, dark brown patina. Very rare with flower and no monogram. "no monograms" this applies to my coin, it is also very rare?
Yes, something like that. The details on your coin are too worn to give a more specific attribution. Also, that green stuff, if powdery, is bronze disease. Search for "bronze disease" on CoinTalk and Google to see various ways to treat it. Left untreated, your coin will fairly quickly be reduced to green powder
If it is bronze disease, do yourself a favor and contact badthad here for his product that treats it. A simply treatment can stop this from damaging the coin further.
You edited this post after I had replied, so I'll amend my reply. I don't think you can determine whether or not your coin is "no monogram" because of condition. Maybe it is "no monogram", maybe not. I don't know anything about the varieties of this coin. The listing you cite mentions "...with flower and no monogram." I don't see a flower on yours (although it too could be present but worn), so this may be an entirely different variety.
