The standard accepted purity for platinum bars is 99.5%. The top producers of platinum bullionⁱ bars are:

• Johnson Matthey
• Engelhard
• Pamp
• Credit Suisse

As with silver and goldⁱ, bars have less of a premiumⁱ than coins. However, platinum is a very expensive metal.  You always want to be confident you are dealing with a safe, reputable source if you are purchasing any precious metal, but especially platinum.

Bars are a great way to invest in platinum because they are:

1. Uniform in size, easy to handle and convenient to store. 
2. Compact, which enables investors to secure a great deal of wealth in relative small storage areas.
3. Readily accepted for resale, making them very liquid.
4. Internationally negotiable.
5. A store of value: it can be jewelry or an industrial metal.
