Does not fit micro SD card
"The coin is designed to hold a micro SD or microfilm hidden within it in order to protect it from prying hands. The build quality is great and it functions exactly as intended while looking exactly like a real quarter, however the compartment cannot compensate the thickness of a standard micro SD, mainly due to the ridge in the back of the card which holds it fast inside a reader. When a card is concealed in the coin, the ridge stops it from closing completely and leaves it much more obvious while also making it much less secure and vulnerable to falling open with not much less than a slight drop. If the compartment was just two millimeters deeper this would be a five-star product."
