Edit: the following appears to be a bug, if it happens report it to SP so they can investigate.
There appears to be a bug in the Piggy Bank when doing certain activities in DC when the Piggy Bank is not full. The bug is inflating the gems in the piggy bank. An example of this happening is visiting the Ancient World. To avoid this issue or to see your true gems in the Piggy bank, always refresh or restart your game. Also, only purchase the piggy bank when first starting DC, as this will give you the true value of the gems in the Piggy Bank. [Update: no longer a bug, so ignore this.]
Side Note: To get the best bang for your buck you should only purchase the Piggy Bank when it is full, which is 120 gems, because the price remains the same regardless of the number of gems in the bank.
