That was my second in-person swap with Alfonso. This one was the largest I ever made - well over a thousand usd. His banknotes are amazing as always. I would strongly recommend exchanging with him to everyone. Thank you again, I look forward to our next swap!

Another incredible swap with GianOlaiz! Despite USPS taking forever to finally deliver the package, all the banknotes were exactly as described, as always! Alfonso was super friendly, helpful, and communicative while the package was lost, and even offered to split the potential loss with me, which was very generous of him! Thanks again, looking forward to our next swap!

Second successful swap with Alfonso. A friendly swap to help each other collection and to enjoy the hobby. Received the banknotes as agreed (and got with few extra notes as gift - same as received last time).
Looking forward to increase the successful swap count to 3. Thanks once again for swapping with me. Happy collecting. |

Alfonso has some really great notes for swap! He sends high quality front and back photos of them, and he makes sure they are packaged safely and securely within the package. He had straightforward communication that never left me feeling confused. He was really accommodating to any concerns I had about the swap and overall was an amazing swapping partner. I have no complaints and would love to swap again!
