Here you go... this is what diligent searching can turn up on eBay if you look around enough. But as always, you need to know a little bit about what you are hunting down.
Both medals were purchased on eBay. The one on the left is cast in bronze, and the one on the right is bronze coated. Both look the same, but the one on the left is the size of the original with the cross at 36mm wide and 41mm high. The one on the right is 34mm wide and 39mm high.
Other differences are that the one on the left has no visible seams on the sides of the arms of the cross and the mane of the lion is curled. The cross on the right has seams on the sides of the arms of the cross and the lions mane is straighter. The borders of both crosses are also narrower than an original VC, but the medal on the left is of far superior quality of the one on the right.
The cross on the right turns up on eBay quite regularly, and the one on the left - less frequently, and sometimes it is usually poorly cast. But you can drop lucky and get yourself a good tailors copy like the example on the left for next to nothing.
Cheers,
