Sword, thanks for the detailed info, that’s really helpful.
 
	My plan had been to buy stackable trays, with circular indents that the entire coin capsule could fit into, as my collection grew.  
	However, looking at the storage options for quads, it looks like they would take up far less space than multiple trays would, considering the limited amount of “circular holes” you could fit on a tray.  The quads obviously can be stored far more compactly, as they all appear to be of a standard size, with just the foam inner varying in sizes to suit? Are the quads easy to open to remove coins?
 
	I notice that quads seem to be the storage method of choice for a lot of members, which speaks volumes!
