Vintage Old Lot of 7 Mercury Glass? Germany? Kugel? Crackle Heavy Ornaments. I have tried to research these ornaments but I'm just not sure if they are Kugel or German.  I have taken photos a few of the round ones have some issues with what looks like the coating inside of the glass. Photo #9 showing the crackle design, #10 shows one has a prominent dark spot, #11 missing a little of the coating small spots I think it is inside, #12 also shows another spot you can see inside the bulb to me this one is the worst, #8 the ribbed tear drop has some wear to the inside coating.  I cannot remove the top too see inside.
