Swap advice for 2026

Hello everyone!

I'm a beginner collector from Brazil. I've been collecting for a few months and I'm starting to do swaps on Numista.

My main focus is swapping my duplicate Brazilian coins (mostly from the 1980s-1990s) for world coins. I'm also open to swapping with other Brazilian collectors for missing years.

I'd love to hear your advice on:

1. Best practices for swaps in 2026
2. Ideal quantity for international swaps (how many coins per package?)
3. Current state of postal services (delivery times, reliability)
4. How do you verify that your swap partner has shipped?

Any tips for a beginner would be greatly appreciated!

Thank you all in advance!

Hello!

1.

I'm not entirely sure if this is what you meant, but when a beginner has few or no ratings on Numista, it is generally common for the beginner to ship first rather than for both parties to send their packages at the same time.

2.

International shipping costs can be relatively expensive, so very small swaps may sometimes be avoided. In my opinion, the deciding factor is usually the value of the coins involved rather than the number of coins or their weight. Of course, there are many variables, such as using unregistered mail to reduce shipping costs, so it is always best to discuss the details with your swap partner.

3.

This varies by country, but in my experience delivery can take anywhere from 7 to 30 days. I have only used registered mail, and so far I have not encountered any problems.

4.

If your swap partner sends the package by registered mail, they will usually provide a tracking number. If they send it by unregistered mail, they may provide a receipt or other shipping information. Of course, you will generally be expected to provide similar information when you send your package as well.

The points above are simply practices that I believe are commonly followed to facilitate smooth and successful swaps. However, every swap is different, and these practices are often applied flexibly depending on the circumstances and the agreement between the collectors involved.

Thank you for the detailed answer! Very helpful.

One more question: for international swaps from Brazil to Europe or USA, which shipping service do you recommend? Is tracking mandatory or can I use regular airmail?

Thanks again!

Since it ultimately depends on the agreement between the two swap partners, it is difficult to say that tracking is mandatory.

In my experience, however, many collectors have preferred registered mail with tracking. Sending coins by regular mail is not necessarily very risky, but from some of the Numista feedback I have read, I have occasionally seen cases where delivery problems occurred.

To minimize the risk of such issues, I personally use tracked shipping only.
