Albanian 5 Franga Ari 1927 V Prova [solved]

https://en.numista.com/catalogue/pieces33325.html

I've found this coin in my inherited collection and have a question regarding it. Information is scarce and counterfeits are aplenty, making me doubt the legitimacy of mine. Compared to shots of self-declared forgeries, mine doesn't seem to have disproportionate lettering (the R in "FR. A. 5" is too short on some of the fakes, for example) or any odd quirks in the engraving.

The crucial piece of the puzzle is the edge inscription. My World Coins book doesn't mention the edge at all and Numista's entry claims it's "FERT FERT". Mine has "FERT" 3 times, while some other sources seem to claim that authentic coins have "AUDERE SEMPER".

For example, this Italian numismatics forum post contains a photocopy of a coin catalogue (Catalogo Montenegro) giving this claim in regards to the ones minted in Rome (1926 R, regular issue), but this coin was minted in Vienna.

So, what is true? Has anybody found out?

Can you post a picture? here it is very common to find them naturally fake in the markets.

I scanned it.

I am not an expert of these coins, but why a coin from the Kingdom of Albania, minted in Vienna, should have the Savoy motto on the edge?
And it weight 2 gr less also.

The edge description  should be AVDERE SEMPER.and should be 25 gram..

Thank you, mine is 100% fake.
