All silver is vulnerable to an imperfection known as milk spots/white spots. As such we do not offer refunds or exchanges.

To protect our customers and ensure the security of every transaction, Castle Coins reviews all orders before dispatch. Orders may be subject to additional verification checks, particularly for higher-value purchases.

If your order is selected for verification, we may contact you by email to confirm your details before we process and dispatch your order. Please ensure the email address provided at checkout is monitored so we can reach you promptly.

To help your order process smoothly:

• Ensure your billing address matches the address registered with your card
• Ensure the billing and shipping addresses match
• Use the same device and network you normally shop from

We aim to process all verified orders within 3-5 business days. Castle Coins reserves the right to cancel any order where verification cannot be completed satisfactorily. In such cases, a full refund will be issued promptly.

If you have any questions about your order status, please contact us at info@castlecoins.co.uk

Currently, we only ship to addresses within the United Kingdom. We do not offer international shipping at this time. We hope to expand to additional destinations in the future, so please check back for updates.

No, Castle Coins is an online-only store. We do not have a physical retail location. All orders are placed through our website and delivered directly to your door.

Unfortunately, we are unable to accommodate requests for specific COA numbers. Each product comes with a pre-assigned COA number as part of the original packaging — we do not assign or alter these numbers. Orders are fulfilled based on the order in which items are picked from our shelves, so COA numbers are allocated on a first-come, first-served basis.

The COA number displayed in our product photography is for illustrative purposes only and is not necessarily the number you will receive. Your item will come with its own unique COA number, which may differ from the one shown in the images.

Please do not contact use about this, we are not interested.

We aim to process orders within 1-3 business days and ship via your selected standard (3-5 business days) or express delivery (1-2 business days) option.
