The listing, Attention Coin Collectors - Swiss 5 Franc Available has ended.
The Swiss franc is one of the most stable currencies on the planet. Thus, Swiss coins that have no precious metal content (that sells at a premium to face value) are still good as money, unlike many other foreign coins that have been demonetized (have collector value only).
One Swiss franc is equal to .8 pounds sterling, so the 5 franc coin is worth 4 GBP in face value. As a collector coin, if in uncirculated condition, it might sell for a pound or so more, but not much higher than that.
Since Switzerland (Confederation Helvetica) still uses the Franc as its currency, the answer is 5 fr. Which translates to about USD $0.05.
I found this in a drawer and have no clue where it came from.
