Underweight Venetian grosso

Does anyone have some information about how to attribute this 1,12 g 21 mm (possibly) Venetian grosso? It is comparable to the Antonio Venier type III grosso, but note the differences in weight, the doge's pose, and the throne of Christ. I have only found three similar coins, all sold by Rex Numismatics in 2024. 

Note how the reverse die is quite similar to the Nicolò Marcello ½ lira.

It's not clear to me that the lettering is consistent with Antonio Venier, but tough to say because of the condition.

… and weight low by ⅓ is not very encouraging.

The clearly decipherable parts of the lettering are S • M • VENETI and TIBI • LAVS • 7 • GLORIA. I'm also not convinced that the partly missing letters are ANTO • VENERIO.

Yes, maybe … NERIO is possible but I don't think it matters since, as you point out, the reverse is wrong.  The others found online are also sufficiently underweight that they are unlikely to be authentic grossi.

Later grossi under Malipiero and Moro are closer in terms of weight but still with different dies. I looked through the plates in Papadopili but no match there either.

It also needs to be considered that the later/lighter styles have sigle on one side or the other, and I don;t think yours has any.
