Hoarding

Tape hoarding

Hoarding is the act of engaging in excessive acquisition of items that are not needed or for which no space is available. Hoarding can also be defined as collecting and holding otherwise scarce items. Some items commonly hoarded include coins considered to have an intrinsic value, such as those minted in silver, or gold, as well as collectibles, jewelry, precious metals and other luxuries.
