In china nothing is tamper proof, because the equipment and packaging is available to anyone that has the money to purchase or lease it. It is better they made the trays easy to open and reseal, that way one could look at the coins. What they should really do is sell the coins in capsules, stacked inside a tube, that way they are easy to store and buyers would be more willing to buy bigger orders, because they are so compact. The trays imply the coins are collectible rather than bullion, but when you make over a million of a given coin it really is just bullion after all.
