These coins I actually all got from Masis. I seem to be a regular customer of his now!
The first is another Alexandrian Nero. I don't know why but I do really like his coins from this period. I got this one mainly because of the reverse since as you can see the obverse isn't the best. I do like that Masis attributes the coins he sells and gives the full dimensions/weight making it easy for me!

And finally a Constantine II that we all know to well but I really liked the patina and the price wasn't too bad.

I won't bother with the attribution details because we all know this type!
That's all for me for now but knowing me I will probably buy something again this weekend.
