Old coin identification

I bought recently two coins.Can anyone help me to identify them?

 

Don't know much about coins but I'm positive the second one is Constantine the Great.

Found the likely coin or coin original...

The first could be some sort of Byzantine coin or just a religious medal. Looks like Jesus.

I'd put them on a coin forum to get exact identification and whether they look authentic. Lots of fakes out there.

 

I would like to know if they are authentic. thank you

 

The link for the roman coin I gave you gives all the specifics on identifying it. Is it about the size of a quarter and made of copper, for instance? If not, then that's a big red flag, right there.

 

The top coin looks like a bad casting and cut off sprue on the nose,probably very modern replica/fake.

 

I see the same..

 

The first one is a Catholic religious token rather than a coin. It could have been proof that the owner had been on pilgrimage, given at the church of the destination.
One side shows the head of Jesus Christ, the other looks like a chalice with a communion host, flanked by two angels.
I agree with Holly, poor casting and the flattened look of the nose is not flattering.
For pilgrimage tokens quality was not an issue. They were mass produced and people just needed them as proof to show at home and on the road.
The heyday of popular Catholicism and grand scale pilgrimages were the 18th and 19th centuries, continuing in some regions until the mid 20th century.
A few Catholics still go on pilgrimage. It is not mandatory, and it is typically a feature of popular Catholicism.

Popular Catholicism is a people's movement within Catholicism, sometimes interlaced with pre-Christian devotional practices. It is often frowned upon by church officials and seen as containing elements of unacceptable superstition, but condoned because it keeps "bums on seats" in the churches.

 

If you go on Facebook and find London Mudlarks, they quite often find Pilgrims tokens and you might get them to id yours since they have a lot of expertise in the area.

 

Thanks to all
