The physical collection

Every ounce has a story—and a specification.

From a sovereign passed down to a newly minted bar, Troy Ledger records what makes each holding physically yours.

Built for the things a brokerage account cannot see.

Record recognised coins or enter an item manually. Quantity, gross weight, purity, provenance, purchase context and private notes stay attached to the physical holding.

Holdings for the objects. Portfolio for the whole.

The collection is both a list of physical things and a single estimated value. Filter the objects; then read the allocation they form.

Holdings list with metal and form filters, fine weight and estimated change

Holdings

Search the collection, sort it, and filter by gold, silver, platinum or palladium, then by coin, bar, round, jewellery or scrap. Each row keeps quantity, gross weight, fine ounces and estimated change beside the object.

Portfolio total value, history chart, acquisition cost and metal allocation

Portfolio

One total from the latest available spot, a history estimated from current holdings, acquisition cost, and a clear split across the metals you actually hold.

The price that sits under every ounce.

Spot is quoted per fine troy ounce. Inspect the history, then read the same ounce through karat and purity so a 22K piece is never priced as if it were 24K.

The common language beneath every form.

Gross weight×Purity×Quantity=Fine metal

Troy Ledger uses precise decimal arithmetic for physical and financial calculations. Overrides remain explicit when a real-world item does not fit the standard formula.
