What you have is a Swiss Franc, it contains no precious metal value but is worth a bit more than $1 in currency exchange.
"Helvetia" is the national name for the country we call Switzerland. You have a standard circulation coin worth face value. At current exchange rates 1 Swiss franc is worth about 83¢ U.S.
Face value unless it is crisp and unfolded.

Assuming that you are asking about a 1981 10 Franc coin from France (KM# 940 - a Nickel-Brass coin weighing 10.00 grams and measuring 26 mm in diameter with an image of high tension towers and electric transmission wires and denomination at center - 50,000 produced in 1981), it is worth about US$2.75 in Uncirculated condition (according to the Standard Catalog of World Coins).
Unless it's uncirculated, $1. Nearly all U.S. bills dated 1969 and later are only worth face value.
The US didn't print any $2 bills dated 1981. Please check again and post a new, separate question.
I have 3 Violet Parkurst number collector plates. Horses in Action collection, dated 1981, 1982, and 1983. Does anyone know the value of them?
Probably a 20 Franc coin from Belgium. At the time it was issued, it would have been equivalent to about $1.60; however, Belgium now uses the Euro, and has demonetized its Franc-denominated coins, so its only value now would be its numistmatic value (that is, its value to a coin collector). Unless it is in uncirculated condition, it is unlikely to be worth more than a few cents, which is also probably its value as scrap metal.
The banner across its top and the green seals on your bills indicate they're Federal Reserve Notes. The last US silver certificates were $1 bills dated 1957.That said, because $100 bills last longer in circulation, anything dated 1981 or 1985 is still only worth face value in average condition.
