Yes, it is a genuine antoninianus by emperor Tetricus I, minted sometime 271-274, probably in Cologne or Trier. Here is some more data about this type: http://numismatics.org/ocre/id/ric....i.56?lang=en
As you can see from the numerous examples on that page, it is not an uncommon coin. The Romans minted large numbers of these, and many have survived until today. What makes your example a bit more interesting, is its provenance, that it is known to be from a hoard, the one found in Mossy Bottom Barn in 1999. A value could be somewhere around 10 €.
