Welcome to CT . Personally I don't collect ancients, but I am sure someone on the ancients forum will be able to help you. I would try posting there for assistance.
Could be a modern replica. Any ancient folks here? @Roman Collector, @roman99, @galba68, @ominus1, @SeptimusT
Probably real A bronze coin from Obulco, a city in ancient Spain. Not applicable. There isn't a "red book" for ancient coins so to determine the approximate value you have to search various archives for the type, factoring in the condition of your coin compared to the similar coins you find in various auction and sales archives, and also taking into account the date of sale of those comps. That said, the quick answer to your question is that it isn't worth a lot of money, perhaps 50 US at most although there are many currently for sale and in better condition for not much more money. Selling it to a dealer might bring you half of that or less. ~2nd century BCE
