Philippines "Commonwealth" Overprint Missing Hyphen

I collect worldwide, used, inexpensive stamps. Going over Philippines, I noticed a used 1936 overprint on a 2-centavos definitive showing Rizal. The overprint is in all caps, with "COMMON" over "WEALTH" (Scott #144). There's supposed to be a hyphen after "common", but this one has no hyphen.



Scott's 1996 catalog doesn't show this variety, so I Googled it and found a few O27a's missing the hyphen being offered for sale, but the only site with the #144 missing the hyphen said a used one sold in 2003 for $715 (https://historical.ha.com/itm/stamp...Lot-050318).

I assume it's a variety, not an error. Has anyone else heard of this stamp?

It is listed in the 2021 catalog, $100 mint and $50 used.

Thank you, revcollector. Not as pricey as I had hoped, but it beats my second-most-valuable stamp: $25.
