Looks like it may even be a broken cork.

some may call it a banded transparent. Onionskins should have an opaque color(uaually white) under the color stripes

Thought to be caused by the iron punty.

Black Jack was my favorite

Some kids also ground or chipped out parts of their shooters to get a better grip for shooting.

Actually I believe them to all be Akro Agate Sparklers.

It is fairly common.

Yes.

I miss the black eye susans

Looks like ground pontil with light grinding and wear that helps hide it?

fairly common in England but there are some rare varieties.

I believe it is a Lutz Onionskin?

Great shot but did that poor boat spend all summer out of the water?

Ric, yes I believe it is a combo of both soil and glass composition. Having been a bottle digger for years I am very familiar with the type of iridescence that is often formed on buried glass. The metallic iridescence I have seen on the aventurine striping of old dug Pelts looks like a slightly different critter to me? But it seems that may just be me

Very interesting and sure does look somewhat similar on at least one. Might be that color of the striping also has a high metallic content?

Great score!!!!!!!!!!!

This is a sheen all of its own found on heavy aventurine on dug Pelts from the Ottawa site. It can look like heavy metallic on some of the thick aventurine. There is some lighter less metallic coating on some other dug marbles but this is pretty exclusive to the heavy aventurine striping on dug from Ottawa Peltiers.

I believe most folks bidding big use sniping programs not wanting to help drive up the price.

Don't be sorry Mikey, You are also correct. I will even call it iridescent when I come visit!

They look a bit similar to NOFs but in hand are different and the white is highly reactive to UV light. Also usually smaller than the NOFs

Looks like one of the dug ones Mike but I think that the way the aventurine reacts does make it "Metallic" per se

Now you have me questioning myself. I believed there were many many more shapes to pieces than I see in that puzzle. I haven't done a jigsaw for over 40 years so now I have to find an old jigsaw puzzle and take a look? actually I thought all the pieces were slightly different in shape and the more I think about I am pretty darn sure the pieces were all different in shape. There was no way you could get the wrong piece to fit in a spot it did not belong. In that puzzle you could build the whole thing with it not even having the picture as it is supposed to be.

In the machine made world I have only seen one true Blue eggyolk Oxblood. I have only seen one folded Master Sunburst. I have only seen one Vitro Helmet with a black stripe. I have seen over a Dozen lightning strikes and more than a dozen scenics

Whats with the identically shaped pieces?

size would be the first question? many new Chinese marbles have folks thinking they have a lightning strike
