Nugg

In the nonprofit fundraising profession of "prospect research," a "nugg" is a small or mid-level donor who has much larger capacity, typically the ability to make major gifts. A nugg's capacity is determined by how much money he or she has, measured by researching the value of their real estate, salary, investments, and other wealth indicators, like aircraft, boats, or valuable art. Nuggs also may have made major gifts before to other nonprofits and charities, but not yet to yours. The term "nugg" is a shortened form of "nugget," as in a gold nugget that an old timey gold prospector would find in his river rock sifting pan after he ventured out to California or Alaska during the gold rushes of the late 1800s.
