Please be more helpful with your comments and explain why they are fakes; I'm trying to learn here! Thank you
Did you weigh them ? they all look like made from the same material but Not silver are you buying them or just looking ?
They look like zinc. Maybe your picture has totally misrepresented the colour, but they don't look like any state of toned silver to me.
These are the type of coins that need to be examined in hand by some one with experience in the series themselves. Without knowledge, a truly honest seller is all you can hope for. Pictures can only do so much in authenticity verification. Specific gravity, weight, diameter, thickness, consistency in reeded edges, and relief are things that cannot be properly examined by pictures. Even grading a coin can be manipulated by creative lighting and photography. My advice: buy a Redbook, and find a reputable local dealer. Oh, and by the way, these are fakes, and lousy ones at that! Google pictures of authentic examples of these coins.
I apologize as you did ask a question that should of been answered with respect . Look at the surfaces and rims to start. The color is off as well as the photos look very grainy That makes a bell go off that the coin was not struck but cast. Next the rims are square proof coinage have square rims MS coinage don't . Next look at the details combined with all of the above spells fake. Some fakes are real good . ....I've seen experience dealers fooled. So it's all about live and learn.
In short, off the top of my head, the dates on the first two coins are of the wrong style, and the CC mintmark on the last is wrong. Hope that helps.
It's amazing how much easier it is to tell on a desktop. Looking at those pictures on my phone does me no good.
