Please help

Happy holidays, everyone!

Can you please help me identify this coin? I tried Google, but there seems to be many similar ones, but none of them matches this design exactly.

The diameter of the coin is around 1.55cm, but I could not record the weight (it is too low for the scales that I have at home). It is also non-magnetic.

Thank you in advance!

 This looks similar both sides

 A cross within a four-sided shape within a circle. 

Two fleur-de-lis within a three-sided shape within a circle. 

 Charles VIII Denier Tournois Limoges 

Either that or something similar with different lettering. It is a start anyway … 

 One example 

N#423642 

Obverse: Two lilies in trilobe 

Lettering: KAROLVS RX FR 

Reverse: Cross within quatrefoil

Lettering: SIT NOMEN DNI B 

 Not sure if yours has two or three fleur -

 Would be better when what little lettering there is can be worked out … 

Could have been this
N#419584

same design but don't know about writing

Thank you very much for all the helpful pointers.

I have reviewed all of the suggested types, as well as several additional examples I found through Google Image searches. However, none of them appear to be an exact match for the coin I have. This leaves me wondering whether one of the following explanations might apply:

1) This particular type has not yet been documented (which seems unlikely).

2) It is the same type as one of the previously identified examples, but because these coins were likely hammered, there may be irregularities even among coins of the same type.

3) The coin could be a later replica.

I am also having difficulty interpreting the lettering, and I believe there may be only two trilobes on the obverse. One small but important detail that seems to rule out most of the proposed matches is the presence of small dots on both sides, located at the points where the half-circles meet.

Thank you again for your time and for any further insight you may be able to provide.

Could it be this denier tournois from the Bourges mint? N#33602

With a bit of imagination one can make out …REX B at the end of the obverse legend. The design is also similar.

See also the example at https://www.inumis.com/shop/francois-ier-denier-tournois-1er-type-bourges-503431/ for an alternative attribution.

I agree that the lettering (not “gothic” or uncial) is more consistent with a more modern coin.

Probably our colleagues from the French side of nunista could help.

 I had a go at a few possible visible letters 

 FRANCISCVS FRANCORV REX //  TVRONVS CIVIS FRANCORV 

If you are correct, then this coin has lettering “FRANCISCVS FRANCORV REX”, which means “KING FRANCIS, KING OF FRANKS”. This relates to King Francis I, and I found this:
N#8226

It is exactly 1.55 cm, but has no dots. After a while, I found another candidate:

N#442088

It has the dots, but is 1.65mm.

I think the dots are more important than the diameter.

The coins were hammered (so, no way to ensure the same size), and struck to a weight standard, not size.  Then, as we can see from some of the examples. a lot of them were clipped after leaving the mint.
