Question on 2 reales

Blackhawk

I have a 2 reales coin that I cannot find in my Krause. The coin is 1773 and from Peru, LIMAE (monogram) mintmark. The only listing in my Krause for this date has the initials JM...the coin that I have has initials MJ. I see that both the JM and MJ were on coins dated 1774, so maybe this was a time of transition. Anyone know anything about this coin or have a listing for it? Thanks!

Here is the coin. I believe it to be real, although it appears that someone tried to add some denticles on the obverse by making a series of cuts in the rim (or maybe someone was just bored at some time in the past)...

It's listed in Cayon, same price as the JM.
