I'm fairly sure I know the answer, but admittedly it's just my best educated guess. A conclusive/scientific answer would require a massive amount of data well beyond what I have, or that I could process even if I had it. Please don't nail me on terms or semantics. (Pun intended.) I know about the Staurogram, which for my intents and purposes is a Tau-Rho. I know about the Iota-Chi, which so very rarely appears on coins that it wouldn't be in the running for #1. I know about the Patriarchal Cross with two horizontal bars, which also appears so infrequently that it wouldn't be in the running for #1. Etc. Oh! And I know about the terms Christogram and Chrismon. Enough caveats? ;-) I'll post my answer at the end of the 7-day poll, and will not allow the poll results to deter me from revealing the answer I now presume to be true - no matter how far wrong the poll proves me to have been. :-o Warning: Sorry, once you vote, you can't change it. At the end of the 7-day poll I will post which emblem received the most votes, but until then you have to vote to be able to see which emblem is winning. :-D OK, enough from me. What do you all think? Based on YOUR knowledge and experience combined, which of the 4 listed basic emblems seems most prevalent on Roman coins during the stated time period?
I voted Chi-Rho for no other reason than that is a very prominent image in my church and I love it.... Hows that for scientific?
