Any shape is mathematical.
No shape is mathematical really unless it has been created by a mathematical formula, but is certainly a geometric shape. But anything which is a 2D or 3D shape is geometric. My improvement: A catenary curve from a mathematical equation such as cosh x, is a mathematical and natural shape. Maby each other arch can be approximated by a mathematical formula.

Not much, both have the same fineness (99.9% pure silver) and they could be the same product. An ingot is just a bar, so it would just be a silver bar of 99.9% pure silver in it. It tells nothing of the size, an ingot can be only a few grams in size, to several kilograms in size, and it doesn't tell you anything of value because of course an ingot only a gram in weight might be worth less than a dollar while an ingot several kilograms in size would be worth over a thousand dollars.
There are a number of places where one could purchase a silver ingot at a discounted price. eBay, for example, has a good selection at bargain prices.

Since silver certificates have not been produced since the 1960's, I assume that you're asking about a privately issued ingot that is cast in the shape of a dollar bill. I would guess that it is worth its bullion value (silver as of October 9, 2007 is $13.45 per troy ounce).
A gold ingot can also be known as a gold bar and gold brick. It is described as a quantity of refined metallic gold of any shape that is made by a bar producer.

The first year for Silver Eagles is 1986 and the US never struck any rectangular coins, it's likely a silver ingot bar.
