Hey everyone
Just thought I would consult a few people on here regarding a coin I have come across.


Macedonia-Chalkidian League, Olynthos-Spartolos-Bottiaia. 392-379B.C.
Bronze (3.23gm., 17mm.) Very Rare.
Reference:B.M.C.5., p.63,3.
Laureate head of Apollo right.
BOTTIAION. Lyre
Now from what I have gathered over the years a number have been sold through CNG approximately 10 although outside CNG there are none that I have been able to find. The primary thing is that this coin is apparently between 392-379BC while the ones on CNG for the most part are confirmed to be minted in 353/2BC so would this make this coin worth significantly more?
Also this particular coins diameter is 17mm which is above the 15mm of all the others on CNG. So would this prove it is an earlier strike, different denomination (double unit v unit?) or is it just an acceptable variation?
By the way if anyone wants to share an opinion on value, grade, condition etc it would greatly help me out.
Thanks in advance for your help and time
