Just a few days before 2017, the weight of this tiny silver coin hinted to me that it was an obol. That's the first time I encounter such a well-known early ancient Greek weighing just 0.74 g. The symbols on both obverse and reverse are strange to me, maybe a trophy there. I also ignore the date and place of mint, nor can I guess the value of such coins.. Glad to read your comments on the approach of 2017. Yeah..
Wow, 7Charles => I love that cool kantharos and shield coin from Boeotia (very cool) Yah, I'm a big fan of these Boeotian shield examples ... sadly, I don't have a kantharos obol-example quite like your sweet OP-addition ... but I do have a couple of pretty neat coins from this place ... wanna see 'em? Boeotia, Tanagra, AR Obol Boeotia, Thebes, AR Stater
Thanks for your comments. I found a similar coin on Wildwinds: Boeotian shield/ Kantharos. It's a federal mint but sadly it was not an obol, rather a hemi- drachm if I remember.
It remains a problem for tose of us into small coins. It is easier to find images of dekadrachms than of fractions of obols. Coins that sell for $20 can not be expected to be found in glossy catalogs and those are the sales that supply our resources.
7Charles => here are a few other examples to compare your OP-addition against https://cngcoins.com/Search.aspx?PAGE_NUM=&PAGE=1&TABS_TYPE=2&CONTAINER_TYPE_ID=1&IS_ADVANCED=1&ITEM_DESC=boeotia obol shield kantharos&ITEM_IS_SOLD=1&SEARCH_IN_CONTAINER_TYPE_ID_1=1&SEARCH_IN_CONTAINER_TYPE_ID_3=1&SEARCH_IN_CONTAINER_TYPE_ID_2=1
