There should be something minor missing on it, you may not see, if that;'s the case, then take to an antique store or collectors item stor, and ask them to check.
The A is part of the designers monogram, Augustus Saint-Gaudens. But it don't matter, the coin is a replica (fake) and has no collectible value. The 1933 Double Eagle is likely the most reproduced coin in US history, the only legal example sold in July-02 for $7,590,020
Likely yes, I have seen fake 1927-D Saint-Gaudens and many other coins of the series, but not a common 1927 Philadelphia issue. It's best to have an assessment done by a qualified professional dealer.
A counterfeit coin is often referred to as a fake or a forgery.
If you mean a 1928 Peace dollar with No mint mark It's the key date to the series the value in VF-20 is $475.00. I suggest you take it to a coin dealer, because I have seen many 1928 S mint coins with the mint mark removed.
What do you refer to as the "the original AUS coin" and why do you think you have a fake?
Look for a seam along the rim edge of the coin which would mean is a casting and fake. Check the weight. An authentic coin should weigh 268.5 to 269.5 grams. Much lighter or heavier means fake.
If you doubt the authenticity of any coin, take it to a coin dealer.

NO it's a fake coin.
Yes, if it has the word "COPY" on it, it is a fake coin.
Your question isn't clear. Are you referring to counter-fiet coins? These are coins made illegally for profit. They are considered fake as they are not minted officially.
Here's a simple pseudocode for the divide-into-three algorithm for the fake-coin problem: function findFakeCoin(coins): if length(coins) == 1: return coins[0] // The only coin left is the fake one // Divide coins into three groups group1, group2, group3 = divideIntoThree(coins) weight1 = weigh(group1, group2) // Compare weight of group1 and group2 if weight1 == 0: return findFakeCoin(group3) // Fake coin is in group3 else if weight1 < 0: return findFakeCoin(group1) // Fake coin is in group1 else: return findFakeCoin(group2) // Fake coin is in group2 This pseudocode recursively divides the coins into three groups and uses a balance to identify which group contains the fake coin until it's found.
