Gold Cast Bars vs Gold Minted Bars

We continue our series of how to buy gold and silver. At some stage during your exciting adventure of investing in physical gold, you will be confronted with the decision of gold bars vs gold coins. If you decide on buying gold bars you have more options as well. In this article, we focus on buying gold bars and specifically Gold Cast Bars vs Gold Minted Bars. 

Gold bullion is refined and transformed into bars, coins and rounds. According to the World Gold Council, small bars and coins accounted for approximately two-thirds of the yearly investment gold. The demand for gold bars and coins have quadrupled since the early 2000’s.

Of course, your goal is important when considering buying gold as well as your available funds. For example, you may be interested in collecting scarce gold coins or you enjoy building a series of collections of a certain gold coin from a certain Mint like the Gold Britannia coin which regularly changes their reverse design.  Or your only goal might be to accumulate as much gold as possible at the lowest premium price as possible.  

Gold bars are widely known as the preferred method of accumulating physical gold due to its low premium above the gold spot price. This can be a bit generalized because certain Minted gold bars can carry a high premium above the gold spot price. The premium that you pay is dependent upon the bar design and production process of the gold bar.

The production technique basically follows the same method that was used for thousands of years. It starts with building molds in the desired design and shape. Metal is then heated into a liquid form and then poured into the mold. The metal solidifies and cools quickly from where it is popped out. 

A modern method of producing casted bars is described by passing melted gold through a die with a specified width and thickness. These dies are clamped between cooling blocks in a continuous casting process. – goldbarsworldwide

  • The sides and bottom of the bar which were in contact with the mold are usually relatively rough. 
  • The markings on the bars are basic. Normally the manufacturer and the bar details. These may be designed in the mold or pressed on later.

Mostly minted gold bars start their lives as Cast Bars. Several steps are added to the process of producing a gold minted bar which is:

  • Brighter and cleaner than a cast bar;
  • The surfaces are smooth and even on all the sides;
  • More uniform in appearance, size and shape;

The manufacturing process of gold minted bars. 

One common method of producing mint bars is to roll a cast bar into a uniform thickness. Another method is to produce a long strip of metal in the casting process. Bars are then cut with a die from these strips to create blanks according to a prerequisite dimension and weight. 

Bars are then moved to a furnace to soften the metal where the striking of designs take place. The bars’ surfaces are then polished, cleaned and dried. From there it is packaged and sealed.

All of this adds to the cost of the bar which becomes more pricey for gold investors as these bars trade at a higher premium above the gold spot price.

Gold bars are manufactured in various sizes and shapes with the price based on the weight and purity of gold. Smaller bars like the 100g bar are affordable and popular to trade with. 

Gold Cast Bars trade at lower premiums above the gold spot price but have less value. Cast bars are the preferred choice for people who are solely interested in buying gold metal in bulk. 

Gold Minted Bars are artistically more beautiful and carry a higher price above the gold spot price due to the more complex manufacturing process and sealed packaging. Minted bars trade at higher values but cost more. 

The choice of Gold Cast Bars vs Gold Minted Bars comes down to individual preference. Gold is gold and both cast bars and minted bars are excellent choices when a person is looking to buy gold to store value and diversify investments for protection against inflation. 

7 thoughts on “Gold Cast Bars vs Gold Minted Bars”

  1. Gold is one of this investments that I say, “I wish I had….”.  Many years ago, I bought silver in minted bars and held if for about a decade.  If I remember correctly, it doubled in value twice in that time. I bought it on a lark and did make money.  I considered buying gold, but of course, it was a great deal more expensive.  With the huge jump in the price of gold over the last 10 years and this year in particular, I wish I had.  Your article has got me thinking again.

  2. I must say this was informative.  All I know about gold is that you should invest in stock.  TO buy it and keep it as a keepsake, that honestly never came across my mind.  But not thing about it, it could be worth more down the line if you do.  I heard of both coins and bars.  You mention Minted bars of gold this one “no”.  The picture you have I love it.  It looks beautiful “I don’t think that is what you want to call it”   See I would want to touch my gold bars so I would not purchase the minted bars but if I had the money who knows.  Thanks again for the information.  Alicia Watts

    • Alicia, you certainly raise a good point. I certainly also like the feel of gold. How about one bar to touch and the rest safely in storage somewhere…

  3. Hi Luis, that was a very informative article. I really appreciate the fact that you give the cons for each type of gold bar. They each have interesting features and I think that a gold cast bar is a good way to start with physical gold. I wasn’t aware that people were also looking for blemishes on cast bars, as it makes them unique. Thank you for all that information.


    • Thank you for dropping by and commenting Cynthia. Keep your eye on gold because there are some fireworks on its way with gold and silver as investments against inflation.
