Hi Guys, I'm new to coin collecting, so I just wanted to get some opinions on these two coins- Both coins were together when I received them, and at least one of the coin's (right side coin) seems to have some features comparable to a high relief 1922 Peace Silver Dollar. If you look at the coin pictured on the right, the spikes on the liberty crown are noticeably thicker and shorter. With the coin pictured on the left, the spikes of the crown seem to appear longer and skinner (specifically the two spikes in between the letter "E" in the word "LIBERTY." Also, I am new to this, so I don't know how to wipe the residue off without it being considered "Cleaned." Any thoughts/feedback would be great!!!
