You have decided to invest in physical silver. You walk into a bullion dealer and are presented with two options: a beautiful display of 10-gram silver coins with intricate designs, and a heavy, boring 1-kilogram silver brick. Which is the better investment?
The Enemy of ROI: "Premium Over Spot"
The "Spot Price" is the raw, live market price of silver. However, you can never buy physical metal exactly at the spot price. Dealers charge a premium to cover manufacturing, stamping, distribution, and their profit margin.
The Trap of Small Coins
Manufacturing a 10-gram coin takes the exact same amount of labor, machine time, and packaging as manufacturing a 100-gram coin. Because of this, the premium percentage on small coins is astronomically high.
If the silver spot price is ₹90 per gram, the raw silver in a 10g coin is worth ₹900. But the dealer might sell it to you for ₹1,100. That is a 22% premium! The silver price has to jump 22% just for you to break even.
The Efficiency of Large Bars
Conversely, large cast bars (1 kilogram or 30 kilograms) require very little manufacturing effort. They are simply poured into a mold and stamped. The premium on a 1kg silver bar is usually only 2% to 4% above the spot price.
Liquidity Considerations
While bars are vastly cheaper per gram, they are harder to liquidate partially.
- If you own 100 separate 10g coins, and you only need ₹10,000 for an emergency, you can sell just 10 coins.
- If you own a single 1kg bar, you cannot saw off a piece of it. You must sell the entire bar.
The Ideal Strategy
If you are investing serious money in physical silver, never buy anything smaller than a 100-gram bar or coin. The sweet spot for retail investors balancing low premiums with decent liquidity is usually the 250-gram or 500-gram bar. Leave the 10g and 20g coins for gifting during Diwali—they are terrible financial investments.
