VLPP with Chi-Rho on helmet

[Nikko]

A dream coin for a Constantine I coinage collector.
RIC 84, the third specimen reported with chi-Rho on helmet.

Nice coin but rather the fourth. There are at least two specimens on NVMMVS BIBLE II and one on acsearch. All from officina B, so it was probably an invention of a single engraver.

Thanks!
I noticed the two from the French database, but I missed the one on ac search. I will looking for it.
The three coins known to me shared the same obverse die IMHO.

Another helmet with chi-rho from Siscia (RIC 61). Also off. B, probably the same engraver.

I’m incline to think the coin recently sold by Roma has a big star rather than a chi/rho.
These are all the clear specimens of RIC 61 I could find
