Saw this posted over on the PCGS boards and figured I would share it here. Never seen it before, looks like it's home made to me. But the most laughable thing is how much its going for currently. http://www.shopgoodwill.com/auctions/Silver-Cigar-Box-with-Roman-Follis-Coin-Inserts-20012396.html
These boxes, in my experience, invariably have a sheet of lead in the base, so don't assume that the weight is mostly silver. Possibly buyers may not know that and assume that the the item is mostly silver with a light wood lining. This may account for the high bids, they think they will get almost 4 pounds of silver.
