Mark WP #47 is one of the rare roof marks.  It has the kanji symbol Wa 和 under a roof.  Wa 和 means harmony.

This float has a perfect stamp with very little wear showing on the surface of the glass.

In Walt Pich's 'Glass Ball Marks' book, he mentions that mark WP #47 has been found on 16 inch floats.  Since this float is 12 inches it may be even more rare than the 'rare' 16 inch size float.

This float has excellent provenance having been found in Japan by Kala & Aragon Ellwanger in 2020.

Maru Ha は is classified as uncommon but this version of the stamp is less common than most.

What makes this stamp unusual is that the two parts of the Ha は symbol are connected.

This float measures 3 inches in diameter.

This Cranberry Dot float is stamped with mark WP #248 'Otera' 寺.  To float collectors, it's also known as the 'Temple' mark.

The seal on this float is a deep cranberry color.  Unfortunately, there's considerable chipping on the edges of the seal.

This float measures about 2 1/2 inches in diameter and was probably made for a Tako jig.  Tako translates to Octopus in Japanese.  

Small 2 1/2 inch float with a Green Seal.

These floats with green seals don't seem to have the collectibility of their blue dot and cranberry seal counterparts but I've come to grow quite fond of them.

Ro Purser made this float in 2020 specifically to sell to float collectors. 

It’s a well-made 4 1/2 inch float able to function at a depth of 500 fathoms. 

The idea for the ‘black cod’ stamp came from Larry McKilligan.  It’s an intricate brass stamp that was hand-made by Ro.

This version of mark WP #344 'Wa ワ Under a Roof' has a set of two marks that mirror each other.

It's less common than the single version.  There have been several floats with the 'mirrored marks' identified in recent years.

This float has a nice yellow swirl that eminates from the seal.  There are also some tiny remnants of shell life.

It measures about 3 1/2 inches in diameter.

This version of mark WP #19 Ki 木 is quite interesting.  The stamp has been pressed deeply into the seal of this 7 inch float.

Typically, mark WP #19 is found on 3 inch floats.  This 7 inch float with WP #19 may be a rare find.

The symbol in the WP #19 mark is Ki 木 which translates to 'tree'.

It's quite heavy for its size and is slightly out of round.  This indicates to me that it may be an older float; possibly pre-WWII.

There are extensive remnants of shell life on this float, too.

I bought this float on eBay in 2020 and it came with quite a colorful story:

"This float was one of many found on Micronesian atolls and islands from 1963 to 1983.  In particular, this fishing float was beachcombed on the island of Saipan, Mariana Islands in the 1970's.

My parents were fanatical float "finders" not collectors.  They traveled on rusty scows like the MV Rananim, MV Palau Islander, MV Yap Islander, and Hafa Adai throughout Micronesia and found what the sea chose to give up.  Thousands of early morning trips to windward side beaches where the majority of the floats were broken on the reef or beach.

Every authentically beachcombed float tells a story."

The Two Dot mark is not that rare but it does remain undocumented since it doesn't appear in any of float books.

This 5 inch float is an excellent example.  I've seen the two dot mark in smaller 3 inch float but I don't remember seeing it stamped on a 5 inch float.

Maker's mark WP #121 is comprised of two symbols:  Sa サ with Sei 井.

This float measures about 3 inches in diameter.

It has excellent provenance. It was beachcombed on Kunashir Island, Russia by Olga & Dmitry Solova.

This is a rare sun-turned Japanese float.

It measures 4 inches in diameter.

Beachcombed on Kunashir Island, Russia.

Mark WP #142 'Nishi Tani' 谷西 in the larger 3 1/2 inch size. 

Nishi Tani 谷西 translates to mean 'west valley'. This mark is embossed on the side of the float.

These floats with mark WP #142 have a unique four piece mold construction.

Produced by the Nishitani Fishing Co. located in Otaru, Japan in the 1930's.

It's harder to find this mark in the larger 3 1/2 size than in the more common 3 inch size.

Very rare mark WP #54 that's been imprinted in the glass, so that the mark is recessed deeply into the seal.

I think there are only a couple of examples of this kind in inset stamp in this mark WP #54.

The float itself measures about 3 1/2 inches in diameter, which is a little bigger than the floats stamped with the typical WP #54 mark.

This float has excellent provenance. It was beachcombed on Kunashir Island, Russia by Olga & Dmitry Solova.
