Looking at picking up a Da Yuan Tong Bao in a ACCA Slab. Are these slabs faked often?

How is the grading company viewed as a whole?

Very new to coin collecting so any info is appreciated 🙏

Kopeck (0.68g), denga (0.34g) and polushka (0.17g) of Ivan IV, middle of 16th century. (on copper 3 kopecks (30.7g weight and 39mm diameter) from 19th century as a background). kudos to this post ("How tiny is a denga?") for helping me to remember about these beautiful tiny pieces

Im thinking of making a small box for my valuable silver coins but i know some wood can really damage silver and i was wondering what wood would be the best that i can easily find, im aware that mahogany and rosewood is good but theres no chance in finding them. And all the coin will be in acrylic coin holders and the inside of the box will be covered in flannel, silk or felt.

Good day,

I was just going through a bulk buy of world junk, and I cam across the coin, based on cursory research I believe it to be

(Previous 2x2 attributes)

Emperor l sigismund medieval Hungary 1387 to 1437

citations are hussar 576 under 449 and then within the

obverse is the patriarchal shield cross

reverse is the part Shields

Does anyone know anything about the 'coin' I don't even know what denomination it could be! Thanks in advance,

Hey there!

I recently acquired this Penny from a buddy of mine who couldn't ID it, and I have been scratching my head for quite a few days now at it as well....

I think based on crown shape alone it's possible it is a Class 11 or maybe 2A?

Anyone have any ideas on this? Also, what you would list as condition?

Thanks in advance for your help!
