I thought they've always been made of some sort of nickel silver alloy or "German silver".
"Nickel-silver" is a marketing term--there is no silver in "nickel-silver" fingerpicks.
From Google:
Nickel silver is named for its silvery appearance, even though it doesn't contain any silver.
Nickel silver is an alloy of copper, nickel, and zinc that typically contains the following percentages of each element:
Copper: 50–80%
Nickel: 5–30%
Zinc: 10–35%
Nickel silver may also contain small amounts of lead, tin, and manganese.
The most common composition is 18% nickel, 62% copper, and 20% zinc.
It's also known as maillechort, German silver, argentan, new silver, nickel brass, albata, or alpacca.
I was told by Doug Hutchens, maker of "Roy's Own" fingerpicks that there are seven hardness grades of the
"nickel-silver" material used for fingerpicks.
The old Nationals used the second softest grade (#2).
Doug chose the softest grade (#1) for "Roy's Own" fingerpicks.
In my experience, Doug's softer "Roy's Own" fingerpicks grab the strings more than the old Nationals did, producing more tone and volume.
