I meant to include the reverse photo with my last post. The die break adjacent to the mintmark does appear very similar to RPM #23 (thank you for that resource). It even has die chips on the reverse on the T in CENT, but they do not appear similar to the ones in the photo of RPM #23. Also, none of the other obverse die markers for 23 appear to be present.
This has had me baffled for quite some time. I swear I see a tilted "S" to the left of the "D" but that could just be wishful thinking.
Thank you for your considerate replies and direction on this.
