It took a bit of research, but I was able to locate the silver sheets as we discussed on the show 01/27.
It's a sheet of 100 1 gram pieces you can break off. The cost is $263 if paid by card.
Another option is 10 10gram pieces at $183
From the web page:
These 100 gram Valcambi silver CombiBars are of the 100×1 gram version, meaning you can break them into 100 individual pieces weighing 1 gram each. Each individual 1 gram bar features a 1 gram indication and the .999 purity as well as a Valcambi stamp. Being able to break these bars down means for greater versatility when selling or trading silver. Unlike traditional 100 gram silver bars, which can either be sold all at once or not at all, these Valcambi 100x1g silver CombiBars give the investor the ability to trade or sell any round-number quantity of silver up to 100 grams.

I think we should continue to investigate, and this is a good starting point. Thanks, George!
