It increases the value on the coin.
The 1994 platinum 1Kg koala coin has Queen Elizabeth II on the obverse. Any value associated with the coin will be due to the platinum rather than the coin itself. Its face value is $3,000, but the current value would be the current bullion value of platinum plus anything from 3 to 5% extra which is likely to be very significantly more than the face value. You would be well advised to look after the coin and take it to a reputable coin dealer for positive identification and valuation. The coin should have a "certificate of authenticity" in the packaging.

In collector value it all depends on the rarity and interest in the coin. Some other factors that effect the value are what it's made of and the metals value. The highest denomination coin produced by the US is the $100 One-Ounce Platinum Bullion coin.
