Fourree or lamination?

[Basileus Nikephoros Antialcidas]

I bought this denarius as a fourree and was thinking after I red some articles about lamination, could this be a lamination defect on an original denarius or it is indeed just a fourree? I thank you all in advance for your answers!

If it is a fourree the interior is coppery. In the photos, it look like lamination or corrosion defects but, is the photo black and white?

Thank you for replying! No the photo is not black and white. That's how it looks and in reality, it is dark with a very small coppery hue only on some parts of the peelings.

I just found a die link! This is the same type with I think the same observe of mine which is in British Museum!

Much more likely official with a die link. There are fourrees made with fake dies impressed from genuine coins but that was most common during the Roman Republic.

The coin shows a seam at the bottom of the reverse that is very characteristic of a fourree.  Copper cores  are subject to dark toning so a lack of red color is common.  If you want to prove beyond any doubt what is going on below, you can cut the coin in half and see the middle but I would be perfectly happy calling it fourree without destroying it.  Experts refuse to allow the possibility that such coins were made in the mint basing this on the fact they have seen coins that most certainly were not.  Nothing is proven 'not' by proving there are other things that are not.  I have no idea who made the coin, where or when but believe you are safe calling it fourree.
