Cool. You got a Decentius in there. That's a great find! Last pic. I'll look you up a Ref. & post in a bit. Top left in the 1st group is a 1/4 Follis of Constantius (as Caesar) from Siscia (only mint that made them). That's a good score. I can dig up a reference for that too ( if you want it). The Constantinopolis commemorative was IDed above (top row R, 1st pic). 1st pic: bottom row; 2 middle coins are Gallienus (Ob: GALLIENVS AVG), L coin looks like a FORTVNA REDVX?, the R one I'm not 100% sure. Then the coin to the L, bottom row, is PROBABLY a Constantius II FTR, soldier spearing fallen-horseman (MM off-flan so basic-type ID). But it might be something cooler. Any chance you couple post a better pic of that one? Neat coins; congrats.
You’ve got Constantius II, Gallienus, Decentius, Constantinopolis, among others. Most of these are easily readable, try looking at the legend and you can figure it out pretty easily
Here are some in glancing daylight. I also put some flax seed oil on them. I can remove it if needed.
Yup, Constantius II FTR, horseman. They look nice, especially for what you were working with; good job. The Decentius especially, nice color.
Flax seed oil is used for a lot of things. I use it to season cast iron. But I bake it at 400 deg. and it makes a hard coating on the iron. It wont hurt these coins at all. So much garbage on the web. I just watched a video of an English old timer who said do not use Vaseline on roman coins, its water based. Maybe the lotion but Vaseline is petroleum jelly. Its oil based. There is also a lot of misinformation on WD40. Some say its fish oil,its not. I have collected firearms for many years. Bought and sold. I have used WD for over 50 years. It works great. There is a rumor that even many gun dealers hold that WD solvent evaporates and leaves a gum behind. This is total BS. I have done several tests where I put a half cup of WD and left it out for months to evaporate. What is left is a 3 in 1 clear oil. What happens is if you us WD on any thing that has crevasses,it will penetrate and break down the grime old oil and dirt built up in places you don't clean. It runs out and when the solvents dry it leaves all that garbage behind. Its not the WD its the garbage the WD dissolves and brings out of those hard to get to areas. I have had someone on my YouTube channel were I did the test say WD is water based. That is absurd. WD is a petroleum based product.
I also used my sonic cleaner with some dish soap on these for about 30 minutes. Helped remove all the easy to remove dirt.
I would recommend renaissance wax if you want. Most oils have some level of acid which isn’t what you want on your coins
