Gold Coin Accounting for Jewelers: Sales, Transfers, Settlement

In gold coin accounting, each coin type is a separate item that is bought and sold by count, has its own rate, and its balance, whether in stock or in a customer’s or trade partner’s account, must be kept apart from money and gold-weight balances. If you record coins like raw gold, only by weight or only in money, your books will get tangled sooner or later. This guide shows how a gold shop should record coin sales and purchases, coin transfers and coin-for-coin settlement. Examples use Iranian coin types and toman (Iran’s everyday currency unit; 1 toman = 10 rials), but the logic applies to any bullion coin.

Why Are Coins a Separate Item in Gold Shop Accounting?

A gold coin has a defined, standard weight and purity, but the market prices it by type and count, not just by weight. Each coin’s price is made of the value of the gold inside it plus a difference the Iranian market calls the “bubble” (hobab), which grows and shrinks with supply and demand. In other words, two items with similar gold content can trade at quite different distances from their intrinsic value.

The accounting consequences:

• Coins must not be merged into the weight stock of finished jewelry or melted gold.
• Each coin type needs its own item code and its own rate.
• Counterparty balances need a coin column, rather than converting coins to money and mixing them into the money balance.

Coin Coding: Which Types Should Be Set Up Separately?

The most common gold coins in Iran’s market are the full coin, half coin, quarter coin and the small “gram” coin. Some shops also separate different designs or mint years, since they sometimes trade at different rates. A simple suggested coding:

A common mistake is to “work out” the half and quarter rates from the full coin. In practice each type has its own bubble and needs its own daily rate. For general item-coding principles, see our guide to gold and jewelry inventory coding. Take the official weight and purity of each coin type from the issuing mint’s published specifications and enter them in your software.

Recording Gold Coin Sales and Purchases

A coin invoice is simpler than one for finished jewelry: there’s no making charge, and instead of weight and purity you need the count and the rate per piece. But a few points shouldn’t be forgotten:

1. Buying and selling rates are different: the shop buys coins at one rate and sells at another. Both should be on the day’s rate board.
2. Check authenticity before buying: coins bought from customers, especially without original sealed packaging, should be checked for authenticity and condition. Set this routine based on trade experience and, where needed, a lab.
3. Fee or spread: if you charge a separate fee, show it clearly on the invoice.
4. Immediate effect on stock: every invoice must change the count of that coin type at once.

Hypothetical example: a coin sales invoice

A customer buys 2 quarter coins and 1 half coin. In this hypothetical example the day’s selling rate is 28,000,000 toman for a quarter coin and 54,000,000 toman for a half coin:

After this invoice, quarter-coin stock drops by two and half-coin stock by one, and 110 million toman goes into cash or bank. Nothing is added to or removed from the weight stock of showcase gold.

Coin Transfers and Coin-for-Coin Settlement Between Traders

In trade and wholesale dealings, many debts and receivables are never converted into money at all. When a trade partner owes you 10 quarter coins, their debt is “10 quarter coins”, not today’s money equivalent. Record it in money, and if the rate moves tomorrow, your books won’t match theirs.

Hypothetical example: coin-for-coin settlement

No money changed hands in this whole cycle, and the account closed exactly. If the partner wants to settle part of a coin debt in money, the conversion should use a rate both sides agree on, recorded on the same document. The same logic applies to gold-for-gold settlement; more detail is in gold wholesale (bonakdari) accounting.

Customer Coin Balances: Three Separate Columns

A customer who leaves coins with you, pre-buys coins or pays part of a purchase in coins should have three independent balances: money, gold and coins. Combining them into one money figure makes statements hard for the customer to read and invites disputes. For statements and dispute prevention, see customer accounts for gold shops.

Pricing Coins in Your Gold Accounting System and Rate Board

Coin rates usually move in the same direction as gold, but not necessarily by the same amount, because the bubble changes too. So:

• Define separate buying and selling rates for each coin type.
• Every time you change a rate, make sure the customer rate board is updated as well.
• On volatile days, give one person the job of updating coin rates so two different rates are never announced at once.

Daily Coin Stock Count

Coins are small, identical and valuable: easy to move, and one missing piece is a big loss. That’s why coin stock is best counted every night by type, separately from showcase gold, and compared with the system balance. A simple count sheet (hypothetical figures):

In this example, the missing quarter coin must be investigated that night. The cause is usually one of these: an unrecorded sale, a quarter coin sold by mistake under the half-coin code, or a transfer delivered before its document was entered. If coins are kept in sealed packs, count the packs as well as single coins. Storing customers’ deposited coins apart from shop stock also makes counting simpler and errors rarer.

Common Gold Coin Accounting Mistakes

• Recording coins as weight gold and losing the count.
• Converting a partner’s coin debt to money in the books without agreement.
• Deriving half and quarter rates from the full-coin rate.
• Not counting coin stock at day’s end; coins are small and valuable and should be counted daily.
• Keeping customers’ coin accounts in a separate notebook outside the main system.

Frequently Asked Questions

Should gold coins be recorded by weight or by count?

By count and by type. Each coin type is a separate item with its own buying and selling rate.

What is a coin transfer?

Moving, or committing to deliver, a number of coins between a jeweler and a trade partner or customer without converting them to money; the balance is kept as a coin count.

Can the half-coin rate be taken as half the full-coin rate?

No. Each coin type has its own bubble, so each rate must be announced and recorded independently.

Can a partner’s coin debt be settled in money?

Yes, if both sides agree; the conversion rate should be fixed at that moment and recorded on the document.

How is tax on coin trading calculated?

Tax rules for coin trading can change and differ by country; review the calculation and your obligations with your accountant.
