I've had one of these Asahi Mint rounds from my first silver order, the other two came through as random picks, and my son had purchased the 1oz bar - he was curious.
Asahi Mint
The Asahi Refining company is based out of Tokyo, Japan - formed in 1952, Asahi has a global presence in mining, distribution, recycling, and institutional investments, and is involved with precious metal assaying, refining, and bullion production. They've also made advancements in production techniques that ensure purity, laser-cut engraving, and the unique frost-finish featured on these 1oz silver logo pieces (Source).
1oz Silver Bar & Round
The Asahi Mint offers these pure .999 silver Asahi Logo 1oz bars and rounds.
Front Side
The front side of the rounds and bars have the text "ASAHI REFINING" with the logo above it, along with "1 OUNCE TROY FINE SILVER 999".
Back Side
On the back side of the bars and rounds, the Asahi logo is alternated and duplicated to create a pattern - making use of the contrasting mirror and frosted finishes.
Sharp looking logo rounds and bar from Asahi Mint, the repeating logo pattern on the backs have a nice shine. Fine silver additions the stack.
