Its nice looks original but it has been in the ground for sometime.Some of these date back to the 1800's there are some on ebay but I haven't seen any like this yet it could be a few bucks(common)or a couple hundred bucks.
Interesting find. Do some research and please post the results for all of us to see. http://numismaclub.com/category/286-coins__paper_money_exonumia_tokens_us_trade_/index.html https://www.ngccoin.com/price-guide/united-states/merchant-tokens-rulau/175/ http://tokencatalog.com
