Those radial lines too way too coarse for my linking.
The
RCM put fine lines in the fields as an aid against fake coins.
I have 6x1 ounce Maple Leaf platinum bullion coins accepted over the counter from Australia's leading bullion dealer
If you are in the mind to buy bullion coins, then do so from an accredited bullion dealer, preferably over the counter, so that you can personally examine them in hand before purchase.
Keep and photograph all of the purchase documentation.
When it comes to sell, you can easily establish your trust and honesty with the new buyer, or
you can sell them back to the bullion dealer more easily, especially if you are able to produce the original purchase documentation.
In some countries,
the sales tax paid on the original purchase becomes a deduction against tax on profits in your on-sell.So, keeping all of the purchase documentation
is important.
Especially so, with large scale bullion stackers.
