This is not funny to me, we are who we are here @TheMarbleConnection.
I let this stuff ride for quite awhile before stepping in.
Yours is a very nice --large sized "Jabo Classic" (a marble made for production and general sales) that shows no damage--pretty rare imho.
These big ones generally show up with little white "Hit Marks"--just from packaging and shipping.
They are quite soft in the world of glass marbles and prone to damage.
As far as showing one like it--good luck is all that I can say--these came in a multitude of color combos--most suck--yours is pretty cool.
Respect to you--just keep it cool.
We do not suck here--we just try to help to ID marbles and keep it cool--
Merry Christmas
Marble--On!!
