One of the most common reasons people contact us is because they’ve come across coins or currency and want to understand what they have, what it’s worth, and the best way to sell it.
This guide is a simple starting point. We’ll be expanding on each of these topics in future posts, but this will help you avoid the most common mistakes and save time.
1. Never Clean It
This is the most important rule.
Cleaning coins, even lightly, can significantly reduce their value. We regularly see items that would have been worth much more if they had been left in their original condition. If you’re unsure, leave everything exactly as you found it.
2. The Appraisal & Sales Process
Every collection is different.
Some items are best sold directly, while others may be better suited for auction or consignment. A proper appraisal helps determine value and the best path forward. Our goal is to give clear, honest guidance so you can decide what makes the most sense.
3. How to Prepare Before You Visit
A little preparation can make the process much smoother.
Keep items in their current holders, albums, or containers. If there are notes, receipts, or records that came with the collection, bring those as well. There’s no need to organize everything perfectly — just avoid changing or altering anything.
4. Understanding Value
Not everything carries significant value, and that’s okay.
Coins found loose in change, especially those minted after 1970, are often worth face value. Similarly, many “error coins” and varieties you may see discussed online are commonly misunderstood.
That said, there are always exceptions — and part of our job is helping you identify what stands out and what may be worth a closer look.
We’ll be expanding on these topics, including more detailed value guides and reference tools, in future posts.
If you have a collection and would like help understanding it, we’re always available to take a look and offer guidance.
