Trying to find some sort of cross reference between PCGS Wiley-Bugert numbers and NGC Wiley-Bugert numbers. PCGS uses Variety numbers like WB-1 to WB 19, etc,, where NGC uses WB-101, WB-103, WB-104, etc.
How do I cross reference between them? [ NGC says: 1856 1/1 VP-001 50C MS, NGC Attribution: VP-001, Cross Reference: Wiley-Bugert: WB-102 ]. [ PCGS says : WB-1 Large O, WB-2 Large O, WB-3 Large O RP1, WB-4 Large O, WB-5 Large O RPD, WB-6 Large O, WB-7 Large O RPD...]
How do I cross reference them? Any help appreciated.

The 3 digit WB numbers are from the 1993 Wiley-Bugert book.
You can view it for free at the Newman Numismatic Portal:

Often these older WB numbers group several die pairs together.
The 2 digit WB numbers are from the 2009-22 Bugert books,
which you can download as free PDFs from the LSCC site:

These newer WB numbers are one per each specific die pair.
I recall these new PDFs reference will reference an older WB number when it maps to a new one.
The VP 3 digit numbers are for "NGC Variety Plus".
I believe these were constructed before the newer Bugert books came out.
It's best to use the new WB 2 digit numbers, as they are as complete as currently possible and should encompass the others.
WOW!!! JUST what I was looking for!! Thank you so much! You guys are amazing.
First of all, Bill Bugert (BB) cross references to the Wiley and Bugert 1992 names in his volumes on die marriages.
In some cases, there is a one-to-one correspondence between a WB-1## type found in their 1992 volume and the WB-# found in BB's later registries because the variety represents only one die marriage. However, in many cases, a WB-1## type in W&B 1992 can be comprised of several die marriages.
For instance, 1841-O Large O (WB-101) is comprised of at least NINE die marriages WB-1, 2, 3, 5, 6, 11, 13, 14, 15.
1841-O Medium O (WB-102) is comprised of two DMs: WB-2 (also called "baseball die cracks"), and WB-3 (lacks baseball die cracks).
I suggest downloading Bill Bugert's Registry of die marriages (6 volumes) to get this cross-reference information, and then using the die marriage labels when possible rather than W&B's variety labels. They are all available for download for FREE!
That's six volumes of Seated Liberty half variety and DM information for FREE!
PERFECT!!!!!!!!!!! thanks everyone!!
