Gold is priced by the ounce. A 50 pound block would be 600 ounces and would cost 600 times the one ounce price. (The reason it's 600 oz. is because gold -- and all precious metals -- are measured in Troy ounces, which are twelve to the pound.)

The current value of a gold bullion in bar form varies depending on the weight of the gold in the bar. As an example one ounce is currently $1445 but 100 grams would be worth $4603. The price of gold fluctuates greatly on a daily basis.

A gold bar must meet the standard conditions of manufacture, labeling, and record keeping. A gold bar is then measured by the scale of troy ounces to determine its value.
It depends on the size of the bar and on the current price of gold. Right now gold is around $1600/oz so a one ounce bar would be worth $1600.
A one gram gold bar costs about $50. A 2.5 gram gold bar costs $122. A 5 gram gold bar costs $243. The gold bars come in incremental sizes of 10, 20, 50 and 100 gram sizes.
A properly stamped 1 gram gold bar is useful as a long term, tangible investment. The value depends on the reputation of the bar's source, the current market value of gold, and the fineness of the gold bar (i.e., 0.9999 is more fine and pure than 0.9995). A hallmarked bar from Credit Suisse is worth more than a bar from some lesser known assayer. To find the minimum base value, get the current value for a troy ounce from a place like Kitco, and divide by 31.1034768. I hope this helps someone.

The value of the bar depends on the purity and weight. It needs to be taken to a silver & gold buyer for an assessment of value.
A 1 ounce gold bar is worth $1449.73 USD. The world's largest gold bar weights 551lbs (250kg), it was manufactured by Mitsubishi Material Cooperation in 2005, it has a value of $3,684,000 USD.
Gold's worth in monitary value, is dependent upon the stocks of the country that have gold. If companies lose money, gold value decreases, so be a smart invester.
