Gorgeous coin. Really lovely surfaces.

I believe your coin is actually RIC VIII 195

-Kurt

P is the officina (or workshop) Prima #1. The D is a series letter separating the issue from coins with other letters or devices (leaves, etc). Trier usually used a two shop system so you find TRS coins as well.

While charts always show P meaning Pecunia, I'll throw out the challenge to post a coin where it does have that meaning. I'm not saying that they don't exist but part of the PSTQ series is more common. How you tell is to get more than one matching coin with just a letter difference. Antioch sometimes had 15 shops making it easier to find different ones.

My coin is not as nice but shows the leaf option and TRS:

Oh my God => that is simply an amazin' looking coin!! (awesome tone => and *ouch* eye appeal!!)

... and ummm, who doesn't notice that it looks a lot like a chocolate coin? ... anyone? ... anyone?

cool coins tj and ds.

the leaf mark on the reverse is pretty cool.

I fear that most references hardcopy and online assume a bit of background on such things or at least the ability to figure it out. RIC, for example lists coins as TRP but under that shows two column that read P and S assuming the reader will figure out that the top listing showed the example mintmark with the first shop in place and that the other columns (here just one) would require dropping the P before adding the S. That probably was a fair assumption for RIC considering the chance that someone buying the books would already know something about the coins but online resources get viewed by people considering buying their first $2 coin and not committed to reading what is offered in the way of instructions.

Perhaps we need a $20 book instructing in the use of the $1000 books but the lack of such suggests no one believes it would sell. I wrote a free page on using RIC to ID coins but very few people read it. Most say it is too long and complicated since they expect RIC to be as simple as the RedBook for US. It isn't. All are invited:

...and remember that the rules changed on some fine details of coin ID as often as the emperor changed his socks.

Also few want to hear when I suggest beginners buy coins with readable legends rather than bottom of the barrel uncleaned. The coin that started this thread is exactly what I believe should be a first purchase. After handling a few hundred of these beginners will not be so hard pressed to see what is missing on lesser coins. I'm not a dealer trying to get you to spend the big bucks - the coins I have for sale are never this nice (those I keep for myself!). It is hard enough to ID some coins when you can read the mintmark and see the style without looking through the dirt only to find the significant parts are off the flan. It is quite possible to learn to collect ancient coins starting when you are 60 years old but it will be easier for anyone who recognizes that it might take more than one or two free evenings to digest.

That coin in the 'test' is the one that I believe should be owned by all high school Latin teachers. There are a few other coins with names in a case other than nominative but most of the are 1st or 2nd declension and much too easy.

I think I have just answered my own question on the reference books. Many of you here have already answered in the link below:
