Silver bars will typically get less expensive on a per-ounce basis as the bar gets bigger. For example, a one ounce Sunshine Mint silver bar may sell for $22.68 while a 10 ounce Sunshine Mint silver bar may sell for $219.60. If you do the math, you’ll see that on an ounce for ounce basis the 10 ounce bar is a much better deal at only $21.96 per ounce compared to the one ounce bar at $22.68 per ounce.
