Your two
fibulae appear to be genuine. However, despite the fact that it looks old and rusty the pin on the small one appears to be a
fake added afterwards. You can see dark staining that looks like glue residue where that pin is attached. Both
fibulae have very
poor surface condition. They were over-cleaned possibly by dropping them in acid. Dirt as well as original
patina were eaten away. Alternately they
had a powdery decaying surface caused by
bronze disease (BD). The bright green on one might
still be
bronze disease - depends on whether it is soft and powdery or not.
You can read many threads in the coin cleaning section that can
help you determine how to clean the BD if you wish.
As for typology don't use Hattat. It is really nothing but the list of one guy's
collection. You can see lots of details on the
forum numiswiki page on
