It's really hard to tell.
Here is the note under the listing of 205C in my 2014 Scott Specialized Catalogue;
"Although Post Office records indicate that 2,463 examples of the 205C Garfield Special Printing were sold, almost all of these stamps appear to have been from supplies of the regular issue No 205.
The actual Special Printings, No 205C, came from a small supply sent to the Third Assistant Post Master General before the regular issue was available. Only 22 examples have been certified as genuine Special Printings."
