1- VAM-22B Discovery coin - polishing lines in UTF similar to VAM-1BQ on page 230 in 1921 scribbles guide book, but slightly different angles & does not have the 1BQ scribbles. Same reverse as VAM-9B WITH SAME POLISHING LINES IN utf. Your coin looks like earlier die state with less die file lines. Later die file lines must have mostly removed breaks at D and AR.
