Onionskin or Joseph's Coat?

[SequoiaBET]

At a glance it could appear to be a 4 panel onionskin, but there are large clear gaps in the 'skin' all around the marble. Does that disqualify it as an onionskin and make it a Joseph's coat? The faceted pontil suggests that it was made in the 1850's to 1880's, before Joseph's coats were made- correct? 

It's 9/16 inch.

Oh, it looks hybrid, even though they shouldn't exist

This was supposed to be an onionskin in my opinion, but then it opened up, making it look like a coat (sixth photo)

Josephs Coat, I have larger Coats with one faceted and one melted pontil though most of them are smaller and have 2 unfinished. Yours is probably older, not exhibiting the Brighter colors the Germans put on them in the late Victorian Era. The earlier ones often have one faceted and one melted pontil and are of a larger size than the latter, the majority being around or just over an inch. They were smaller and had two unfinished pontils making faster production for the ever increasing English game board market. The smaller size of yours's does surprise me a bit though, still a Josephs Coat IMO.

My opinion is onion skin, Joseph coats don’t have the white or yellow skin under the color layers, and Joseph coats does not have the clear coat incasing it all.
