Style Coin

How can I identify a Trajan coin? Do you know a good website with pictures?
I have a coin I cleaned, it seems to be Trajan based on the style. I am looking for a link to website that has good pictures. Please include a link if you have one.
Thank you everybody.
Best way is to compare it with other, known coins of Traianus. Try http://www.forumancientcoins.com/roman-coins.asp?vpar=409&pos=0 It depends on where it was minted. Western coins in Latin may have “NER TRAIANO” and a recognizable portrait. Greek coins of Traianus have “NEP TPAIANOC” and a stylized portrait of a Roman emperor. Not all coins, though, would have an inscription and/or a portrait of the emperor.
