The question seems to be asking about two different types of "pounds": one as a unit of weight (the pound of feathers), and one as a unit of currency (the British pound).
A pound of feathers: This is a measure of weight. In the avoirdupois system (which is commonly used in the US), a pound is defined as exactly 0.45359237 kilograms.
A Great British pound: This is the unit of currency in the United Kingdom, often symbolised as £. The weight of a physical £1 coin, according to the Royal Mint, is 8.75 grams.
So, if we are comparing the weight of these two "pounds," a pound of feathers is heavier than a physical £1 coin.
