Ten Troy Ounce Bars

Ten troy ounce bars are a great pick for those aiming for a heftier platinum investment. Here are some reasons why:

But what makes these bars more economical? The lower premium per ounce of ten troy ounce platinum bars is attributed to the decrease in manufacturing costs relative to their size, resulting in a lower cost per ounce over the spot price for larger pieces. In addition, these bars have a relatively high level of liquidity in the market, making them a favorable investment option due to their ease of sale or exchange.

One Kilogram Bars

For those seeking a significant investment in platinum, one kilogram bars are an ideal option. These bars offer the benefit of lower premiums compared to smaller sizes, thus maximizing the investment value.

Typically, the dimensions of a standard one kilogram platinum bar are approximately 53.00 x 117.00 x 8.00 mm. The average cost of a one kilogram platinum bar ranges from $31,000 to $32,000, making it a significant but valuable investment.

The Importance of Purity in Platinum Bars

Purity takes center stage when investing in platinum bars. Platinum, as supplied to industry, contains very low levels of impurities, making it one of the purest metals refined by chemical means. The higher the purity of a platinum bar, the more valuable it is.

To guarantee the purity of platinum bars, manufacturers provide an assay certificate. This formal document provides assurance regarding the purity of the platinum bullion and validates their authenticity and purity. It confirms that the platinum bar complies with the designated purity criteria. For instance, the 1 oz Valcambi Platinum Bar is composed of 99.95% pure platinum.

Fineness Standards

Fineness standards play a pivotal role in determining platinum bar purity. The typical level of purity for platinum bars is 995, meeting the standards for investment grade. A purity of .9995 or higher indicates a high degree of refinement, ensuring the quality and purity of the platinum.

The fineness of platinum bars is determined by calculating the weight of fine platinum in relation to the total weight of the bar. Greater fineness signifies greater purity and can lead to an increase in the value of the platinum bar.

Assay Certificates

Assay certificates are instrumental in confirming the weight, purity, and authenticity of platinum bars. They serve as evidence of the bar’s superior purity and genuineness.

An assay certificate guarantees that the bars adhere to the purity standards established by the mint or the specifications for a particular bar. Purity verification holds great significance as it serves as evidence of the bar’s purity and authenticity.

The primary elements of a platinum bar assay certificate usually consist of details regarding the weight, purity, and authenticity of the bar.
