Silvertone real Coin button covers

Silvertone real Coin button covers. These are an excellent condition. I don’t know much about them. I found them at an estate sale in Portland, Oregon. Top coin: This is a 10 New Taiwan Dollar coin from Taiwan. The obverse features a portrait of Dr. Sun Yat-Sen, the first president and founding father of the Republic of China. The reverse side has a "10" with hidden text that translates to "the country is prosperous and at peace" and "the people live in safety and happiness" when tilted. Middle coin: This coin is a 5 New Taiwan Dollar coin, also from Taiwan. The Chinese characters "圓伍" (Yuán Wǔ) translate to "Five Yuan" or "Five Dollars". Sorry Bottom coin: This appears to be a 5 Cents coin from the Commonwealth of The Bahamas. The reverse depicts a pineapple, a national symbol of the Bahamas, along with the denomination "5 CENTS". The obverse typically features the Coat-of-Arms of The Bahamas.
