You should start a new thread, with clear, focused pictures of the front and back of 1 or 2 of the coins. If the pic is tiny or blurry, it isn't...
Unless it's in a slab, you don't have one. All 5000 were slabbed by Ms. Goodacre after she received them as payment from the mint...

The problem you run into is that this CANNOT occur during the minting process. There are no other coins that use a crude, large five, so it can't...
@JayF You may want to take a look in your redbook and check the weights of a Sacky. The OP said his weighs 6.4 grams
