Terms of Use

Last updated 9 November 2026

1. Who we are

“We”, “us” and “our” means NumiCrown, the trading name of Adrian Kwiatkowski, United Kingdom. The website is numicrown.com.

You can reach us at [email protected] or through the contact page.

By using the site, or by creating an account, you agree to these terms. Please read them with our Privacy Policy and Refund Policy.

2. The catalogue

NumiCrown is a reference catalogue of British Empire and Commonwealth banknotes. The catalogue itself (every country, Pick number, variety, signature and photograph) is free to read, with or without an account.

  • The information is given in good faith for reference only. Dates, attributions, serial numbers and sale records can contain mistakes, and we cannot guarantee that they are complete or correct.
  • We do not value, authenticate, buy or sell banknotes, and the site is not a marketplace. Please do not rely on the site alone when buying or selling a note.
  • Sale records and the price guide show what notes have sold for in the past. They are historical information for collectors, not financial or investment advice.
  • If you find a mistake, please tell us. Corrections are always welcome.

3. Your account

  • Anyone can browse the catalogue, at any age, without an account.
  • An account is free. You must be at least 13 to open one, and give an email address that is yours.
  • An account is for one person. Keep your password to yourself; you are responsible for what is done under your account.
  • You can delete your account at any time by emailing us. See the Privacy Policy for what is deleted.

4. Comments and contributions

  • Comments must be about the banknotes themselves: varieties, corrections and information. Comments about buying or selling notes are not allowed.
  • Every comment is reviewed before it is published, and may be edited or removed at our discretion.
  • When you send us photographs, scans, serial numbers or other material to add to the catalogue, you confirm that you are free to share it, and you allow us to publish it on the site, credited to its source (and to you, if you wish). We quote facts and credit the source; we do not republish whole articles.

5. NumiCrown Pro

  • Pro is a paid plan that opens extra parts of the site for a fixed period: the sales history, the serial number register, the price guide and the records behind them. What each plan includes, and its price, is shown on the Pro page.
  • Each plan is a single payment for a fixed period, and nothing renews on its own. When the period ends, the Pro sections close again and nothing more is charged. A plan bought while another is running adds to its end date.
  • You must be 18 or over to buy Pro, or have the permission of a parent or guardian.
  • Pro is for your own use, on your own account. It may not be shared or resold.
  • Prices are in US dollars and include VAT where it applies. In a few places outside the UK and EU a local sales tax is added at checkout; the checkout always shows the final price before you pay.
  • We keep adding to the catalogue, and the Pro sections may change as it grows. If we take away a major part of Pro while your plan is running, you can ask for a refund for the time left (see the Refund Policy).
  • Pro can also be given free in return for material that helps the catalogue (see the free trial page). A free period is not a purchase and carries no refund.

6. Payments

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders: it takes the payment, accounts for any VAT or sales tax, issues the receipt and handles refunds. Paddle’s buyer terms apply to the payment. We never see or store your card or bank details.

For a question about a payment you can write to us, or to Paddle at paddle.net.

7. Fair use of the site

You may read, print and save pages for your own collecting and research. You may not:

  • copy the catalogue, its sales records or its serial register in bulk, or with software that downloads pages automatically (“scraping”);
  • republish, sell or share the Pro records, or the catalogue as a whole, elsewhere;
  • try to get round the Pro and account limits, or interfere with how the site runs.

We may suspend or close an account that breaks these terms. If we close a Pro account for a reason that is not your fault, we refund the time left on your plan.

8. Keeping the site secure

  • You must not try to get into parts of the site, its server or its database that are not open to you, and you must not upload or send anything containing a virus or other harmful code.
  • You must not attack the site, for example by flooding it with requests so that it slows down or stops for others.
  • Doing any of these may be a criminal offence under the Computer Misuse Act 1990. We will close the account concerned, and may report it to the police and give them the information they ask for.
  • We take reasonable care to keep the site free of viruses and malware, but please use up-to-date security software of your own as well.

9. Links to other websites

The catalogue links to auction houses, grading services, museums and other websites, so that you can see a record at its source. We do not run those websites and are not responsible for what they show or how they treat your information. A link is there for reference only and does not mean we recommend the site or the people behind it.

10. Who owns what

  • The catalogue’s text, its arrangement and its database belong to NumiCrown.
  • Banknote photographs remain the property of their owners, who are credited beneath them, and may not be reproduced without their permission.
  • If you own a picture or text on the site and want it credited differently or removed, email us at [email protected] and we will deal with it promptly.

11. Availability and liability

  • We try to keep the site running and correct, but it may sometimes be unavailable, for example for maintenance.
  • We are not responsible for losses that come from relying on the catalogue’s information, such as the price paid for a note, or for losses we could not reasonably foresee.
  • Where we are responsible, our liability is limited to the amount you paid us in the 12 months before the claim.
  • If something you get from the site, such as a download, damages your device or other digital content because we did not take reasonable care, we will repair the damage or pay you fair compensation. This does not apply to damage you could have avoided by following our instructions or installing a free update we offered.
  • NumiCrown Pro is sold for personal use. If you use the site for a business, for example as a dealer, we are not responsible for any loss of profit, sales, business, goodwill or opportunity, or for any indirect loss, however it arises.
  • Nothing in these terms limits our liability for death or personal injury caused by negligence, for fraud, or for anything else the law does not allow to be limited, and nothing affects your legal rights as a consumer.

12. Complaints

If something has gone wrong, with the site, the catalogue or a Pro plan, please email us at [email protected] and tell us what happened. We will reply within 14 days and try to put it right. For a complaint about your personal information, see the Privacy Policy.

13. Changes to these terms

We may update these terms as the site changes. The date at the top shows the latest version. If a change affects a Pro plan you have already paid for, we will tell you by email, and the terms you bought under apply until that plan ends.

14. The law

These terms are governed by the law of England and Wales, and disputes go to its courts. If you live elsewhere in the United Kingdom, you may also bring a claim in the courts where you live.
