Good Morning, I have come across these 3 Roman coins which have been tested to confirm that the metal content is silver with small quantities of copper also present. I've attempted to identify them but not really sure where to begin. Any help would be appreciated. Images below. Thanks
Here’s a useful place to search http://numismatics.org/ocre/ on the reverses you have : Fortuna standing (Hadrian) Crossed cornucopia and caduceus (Antoninus Pius) Fortuna seated (Trajan)
Since you asked on how to identify the coins, and not for an identification: this website (http://numismatics.org/ocre/identify) allows you to identify roman coins from the imperial period (i.e. after Julius Caesar). You provide all readable legend in the search boxes (e.g. for the first coin I would write "*DRIANVS* - the * should be placed in place for all unreadable legend; with "PMTR*OSIII" for the reverse. This will then result in 145 hits: http://numismatics.org/ocre/results...ANVS*+AND+rev_legendCondensed_text:PMTR*OSIII which can then be narrowed down to 78 if you specifiy the denomination (denarius). By then, simply scroll through the examples and refine your search if necessary.
Welcome to Coin Talk - those are three very nice looking denarii (plural of denarius). In addition to the links provided already, Wikipedia has an article on the denomination denarius that might be useful to you: https://en.wikipedia.org/wiki/Denarius
