I'm pretty sure it's worth more than $1. 2 Swiss Francs are worth 2 dollars alone. I would pay $4/$5 for the lot.
Then you’d be throwing money away. Why would you pay $5 for a partial 1987 mint set that’s not worth above face value?
You have to buy what you like. If you don't know what something is worth, maybe you shouldn't buy it until you are more comfortable in judging the value.
The cent , five cent and dime are common but uncs worth maybe a quarter, the 2 francs is worth about $2 exchange rate, if you are in Switzerland, here as mentioned it is a junk box item 25 to 50 cents, the half dollar is probably the best item in the group since it is a mint set only coin probably worth a couple dollars, more if it is a higher end unc.
Frankly, buying coins such as those, unless they fit specifically into your collection, is junk accumulation.
