A Guide to
Looking to sell a collection you inherited or resell a precious item from your own set of numismatic examples?
Speak to our team of world-class specialists with a combined experience of over 200 years. They can advise on coins, banknotes, military and commemorative medals, tokens, and books.
Our complimentary valuation service is the best way to sell your collection. You’ll be equipped with the best course of action to achieve the highest price, be that a direct sale or a consignment to one of our high-profile auctions around the world.
The world of numismatics is an extremely complicated one, and there are many factors that make these items valuable (such as rarity, condition or age). Therefore, the most accurate valuations are always made when we are able to see the item/s in person.
Valuations by appointment
Visit our store located at 399 Strand in the heart of London, just a few minutes walk from Charing Cross Station. Valuations take place between 9.30 am and 4.30 pm (GMT), Monday to Friday.
We always recommend booking an appointment beforehand.
Valuations by email
We appreciate that not everyone can make it to London. You may get in touch by emailing us directly on:

We receive many requests for valuation on a daily basis but endeavour to get back to you as soon as possible.
Please do not submit these on social media sites (Twitter, Instagram, Facebook).
Baldwin’s reserves the right to make a charge to cover the cost of our time in the case that valuations require a large amount of research.
We receive hundreds of images of coins every week and are always delighted to see them. After all, there is nothing we like better than looking at coins.
If you are looking to send us images of your coins or collections, please follow the guide below.
Most of the photographs we receive are taken with smartphones and that is absolutely fine.
Smartphones today carry a large pixel rate and can produce quality images if done correctly.
All of the images below were taken using a smartphone!
The more information we receive about a coin or item, the more accurate we are able to be.
If you plan on sending pictures of your coins or item/s, for a more accurate valuation please ensure that you have included the following:
- High-resolution JPEG images of both sides of the coin or items.
- The type of metal (i.e. silver, copper, etc).
- A full description of the item/s, including where it was acquired (if known).
- The dimensions of the item/s (27mm, 3.4g for example).
How to submit good valuation photos:
Read these tips from our specialists before submitting your photos for valuation
Place it on a plain background
Anything as simple as a sheet of paper will reveal the outline of the coin — an aspect that’s very important for specialists to examine.
Get close to the coin
We would like to see every detail of the coin – all its markings and tones.
Place it within the frame
Images such as these hide important details.
Watch the cropping
We need to see the whole coin in the photo – images such as the one above are impossible to grade.
You may have to move a bit to make sure that your phone is not casting a shadow on the coin.
Keep the hands steady
Blurred or obscured images make it very difficult for us to identify what your coin is worth.
Don’t hold them!
If you are holding the coin, as in the image above, then you are more likely to obscure some of the item. Place your items on a flat surface rather than holding them.
Send us only your best examples
Too many images makes it very difficult for us to see what’s in there. Choose a few images of some of the more choicer or important items.
What we require:
- Place the coin on a plain and uncluttered background.
- Try not to get too close so that the whole coin sits within the frame of the photograph.
- Watch the lighting, and keep a steady hand.
- No fingers, and if you can send both the reverse and the obverse then all the better.
Remember: the better the image, the more accurate we are able to be in our valuations.
