Australia 1925 Florin

I ordered a coin from your internet site, clicked on the desired coin, paid my money and filled in the postage sections, but a different coin arrived. It did not appear to be in the same condition, but without comparing the two coins I cannot make a true judgement. The 1925 coin (one hundred years old) was part of a wedding present, and there was no time to return it or complain. I have purchased sovereigns previously and always received the coin shown on the website. I thought that this practice would apply to florins as well.
