I don't think there are any grading companies in South America
Here a post I made just the other day regarding this:
I have some coins that I was thinking about having graded, but I have a few questions. My coins have just been sitting in a box in a safe, rarely seeing light for over a decade. They are not mint, but certainly in great shape. Is it worth getting them graded? I also remember reading that some services no longer grade these coins. So what are the ones that do grade them still, and which is the best to go with? Can I hand deliver them to the facility? I would be pretty nervous shipping such a high value item, even with insurance. Is there anything regarding grading that I need to be aware of?
Depends on what your long-term goal is for these coins/collectibles.
I prefer my coins graded/slabbed to give them more protection and know that they have been authenticated.
ANACS no longer grades physical cryptos. They stopped in about 2019.
NGC is currently grading physical cryptos, but seems very limited to only Casascius coins at the moment
PCGS is currently grading physical cryptos, but only way to submit is to mail-in to them or drop off in person at a coin show
ICG is currently grading physical cryptos, they DO allow walk-in service if you call ahead and set it up with them.
Cost can vary from $25 up to $150+ depending on the service tier/turn-around time and then also the value of said crypto collectible.
Due to the value of certain collectibles like Casascius and similar, I would no longer recommend shipping these items.
Insurance will not cover the value of the digital load of loaded collectibles. This is similar to shipping a gift-card.
