any suggestions on value or where to look for a value

I came across this coin recently and purchased it. i thought I was making a good deal to resell but even my local coin dealers say it isn't their specialty and do not make an offer. Basically I have no idea what it is worth and the guy I bought it from said he paid around $150 for it.
