It really depends on the coin's value and the country that issued it. If it's valuable you may want to try to sell it privately either through eBay or an auction house. In addition you may want it to be professionally graded.
On the other hand, if it's not worth much (for ex. a very worn 1915 US nickel, retail value $5 or so) it may not even be worth selling because it would cost more to post on eBay and a dealer would only pay wholesale, around 3 bucks.
You can sell a 1915 five cent coin at a local coin shop, through online auctions or marketplaces such as eBay, or to a coin collector or dealer. It's a good idea to research the coin's value before selling to ensure you get a fair price.
