Welcome. The reason that I participate in this forum is at least partially because a good proportion of the members don't take themselves as seriously as you might find elsewhere. We do have quite a range of posters and a similar group of lurkers but perfection is neither a requirement nor benefit of membership. I suspect you will find you know more people here than you might have guessed. BTW, reading later Alexandrian tets is very much an acquired skill. The later ones like Maximianus and Diocletian seemed to try hard to cut legends in tiny, cryptic letters. I find it useful to look for what I would call a typical letter that can help direct your eye to the rest of the reading. For Maximianus and Galerius, it is the Ξ. For Diocletian it is the tiny o in DIoK. You don't make ID's on these alone but you wonder why they are not there id they are not. The nice Aurelian as shown here is easier to read from the Λ ΔOM than from the Aurelianus part. That is not unusual. I remain amazed at the number of lower grade specimens with perfectly clear AK and CEB but no other legible letter. Experts (not I) might learn to read the letters like kids today must do if they have a grandmother who writes to them in cursive. I will warn that this particular group includes a few people who like late Alexandrians and are working on the skills.
It's particularly embarrassing since I've been almost continuously actively collecting and studying since the 2nd Eisenhower administration, and among the first batch of ancients to come my way (in 1957) were two Alexandrian tetradrachms - Tacitus and Philip I. Of course, it would have been doubly embarrassing if one of those originals had been an Aurelian, so I guess it could always be worse. There doesn't seem to be a mood emoticon for "embarrassed" - too bad, that would be more appropriate.
It's ok to mistakes, doesn't matter how long you have been collecting. We have many people here that help each other out and they know quite a bit. Besides I've been collecting for a few years now and I still can't ID most coins without triple checking them online.
