There's no such thing as a 1907 walking liberty dollar. For starters, there were no silver dollars minted from the years 1905 to 1920. Secondly, the walking liberty design was featured on the HALF dollar, but not until 1916.
All genuine walking liberty half dollars are 90% silver for all years. Unless there is an obvious reason why it wouldn't be silver (wrong year, wrong design, plating flaking off, etc.) it is safe to assume it is silver. There are a few contemporary and modern counterfeits of Walking Liberty dollars but they are easily spotted.
No. That design was used on half dollars struck from mid-1916 to the end of 1947.No silver dollars were made during the years 1905-1920 inclusive.No. The Walking Liberty design was only used on halves from 1916-1947 until 1986 when it was chosen for the American Silver Eagle bullion coins. No U.S. one dollar coins were struck in 1905
