How Do I Tell The Difference?

[bermar]

I have always had difficulty telling the difference between transitionals.

First, please help with these, and second, please discuss how to know

the difference between Navarre, Leighton, M.F.Christensen, German, and Japanese.

Thanks for any help.

Navarres are Leightons and will have melted pontils(occasionally they show up with an extremely tiny pinpoint pontil without melting. The earliest German types(previously known as Leightons) have a ground(faceted pontil) MFCs usually have a nice tail and a long smooth cutoff. The Japanese types usually have an extremely rough(spider web like) cutoff area. I believe the others from the tiny 1/32" indent type to the various crease pinch etc cutoffs are German. I also believe there are a bunch of German handgathered slags(Transionals)that appear just like many American HG slags. The Melted pontils and ground pontils are actually handmades and not really transionals.(handgathered-machine rounded)Edit, now if we could just figure out where the so called Canadian types come from(although I am starting to think Germany)

i wil say ditto to what Galen says. Very Good!

[bermar]

Thank you.

Still not real sure.

Can you tell from my picture which pontil type these are?

Thanks again

The first 2 look like ground pontils as seen on handmades.The third one looks like a short cut off the same as I see on my German slags.

Very nice marbles. The white one is an excellent example. What size?

They are melted pontils.

The two showing the most purple/white appear to be from Navarre, Ohio, which was one location of James Leighton's marble making plants. The colors and the "looping" out of the pontil are charactistics of marbles coming from this plant. I would say it is very possible for the white one comming from this location also.

thanks.

Thanks everyone.

They are between 21/32" and 11/16".

A friend brought them over and asked me to either buy them or sell them for him?

Any ideas regarding fair prices?

Agree with 1Dan$ that all have melted pontils --

Another interesting one from the same source --

Never mind, can't get the link to work. Sorry! By the same guy, Roger Browse. Maybe you can get to it by just googling him - - -

Pretty much mint.

At worst, a micro pinprick or a small rub.

The white one is mint with a small flat area at the top right of the "9".

Thanks for asking.

Thanks IDans, I always have had difficulties to see the difference between regular-ground or melted pontils.

Even when I look for minutes at the different pontils I can hardly see it.

Hope one day I will learn it.

That size usually goes for 40- on the bay.

Good photos!

[winnie]

Thanks IDans, I think I got it thanks to your pictures.

Ground,you can hardly see the pontil

Regular you see where the cane is knock off.

melted you see more of a twisting movement.

thank you so much.
