Place 1/2 of the chocolate in a microwave-safe bowl. Microwave on low until almost melted, about 1 minute; do not allow chocolate to burn. Remove from the microwave, stir to melt any remaining pieces, and let cool slightly.
Drop a small handful of coffee beans into the chocolate and drench until completely covered. Fish out with a fork and drop onto waxed paper, making sure beans are separated. Repeat with remaining beans. Let cool until chocolate is solid, about 30 minutes.
Meanwhile, melt remaining chocolate in the microwave; do not allow to burn. Stir once and cool slightly, about 2 minutes. Drop a small amount of chocolate-covered coffee beans into the melted chocolate at a time, until completely covered with a second coating. Place on a new sheet of waxed paper and let cool completely, about 30 minutes.
