Gouby BP1881Ha (P+p) with 11 1/2 teeth date spacing

[absence of uniformity]

"One Penny 1881H with Low H, almost in contact with the linear circle, the top of the H just below the line of the base of the numerals, Gouby BP1881Ha (P+p) with 11 1/2 teeth date spacing"

Can I ask please anyone with Michaels specialised book is there a estimated rarity listed for BP1881Ha (P+p) with 11 1/2 teeth date.

Searching this forum no results are found. As far as I can see BP1881Ha (P+p) with 11 1/2 teeth date is not listed on Richard's website.

A single example of  BP1881Ha (P+p) with 11 1/2 teeth date is listed on LCA without reference to rarity. The coin however did sell for £300 listed as UNC.

A similar grade coin with the same die pairing without the wider date and low H sold for 1/3 of that price.

What I'm trying to figure out is the 80% remaining luster responsible for the tripling of the sold price or is it the low H and wider date.

 

Thanks.
