250 Gram Silver Bars
You can buy 250g Silver bars from BullionByPost, for investors wanting to invest in slightly larger units of silver. The 250 gram bar is available in two different styles - a minted bar made by PAMP and a cast bar by Umicore. Both of these contain exactly 250 grams of 999. fine silver, and are made by LBMA-approved bullion refiners.
There are 2 main ways of creating precious metal bars:
Cast Bars: Casting has been used for thousands of years and is often referred to as also "molded" or "poured".
Casting is a cheaper process, and while it creates abnormalities and blemishes, these are unique to the bar, meaning no two are the same.
Minted Bars: Minted bars tend to carry a higher price than cast bars due to further manufacturing input required for cleaner and more craftsmanship required in the finishing and embedded designs.
Generally minted bars are more visually more aesthetic to the eye, as this can also involve further manufacturing stages for polishing and cleaning.
