1819 B-1 Bust Quarter G-T-C : 200 Year Anniversary

For the first month of 2019, I start with the 1819 Browning 1 variety bust quarter. It has the large 9 in the date, is considered an R5-, and has interesting die states if you like die cracks. The mintage for 1819 bust quarters is only 144,000 coins, represented by four varieties. The only silver coins produced by the mint in 1819 were quarters and half dollars.
The first coin below is my example, which was crossed from NGC to PCGS. Feel free to guess the NGC and/or PCGS grade if you'd like, and comments are welcome. If you have an 1819 B-1, please post a picture if you're able.

This second coin is an example of the later die state with a die break across Liberty:
Searching for bust quarters.....counterstamps, errors, and AU-MS varieties, please let me know if you can help.

Very nice 1819 B1 quarters!
I'll guess 48 and 51
I have a number of 1819 quarters, I'd post pictures but we lost the index box to our stored photos in the last "forum upgrade " so we're sol on that front.

I don't have a B-1, but do have a B-2 which is also a large 9 variety. Apologies for a premature post if you planned to get to this variety later.

Nice coins! I would ping yours at 45 for the first and 50 for the second, depending on luster and quality of surfaces, and the mood of the graders that day. Herez my B1. Mine is also the late die state with a crack through the cheek of Miss Liberty.
Best, SH
XF45 in its new PC holder, and beautiful.

The first coin was an NGC AU58, and it crossed to PCGS AU55, which @jughead1893 guessed.
The second coin (LDS) has AU details, but is a whizzed coin.
Thank you to @basalstate for posting your B-2, and @spacehayduke for posting your B-1.
Thanks for the comments and taking a look.

Here’s mine, graded G4 by PCGS. It’s well worn, but it’s a B-1.
