A professional certificate makes your item more trustworthy, more presentable, and easier to sell in the collectible market.

How it works

1. We advise you to get a pre-assessment before the certificate to confirm the item's potential and avoid unnecessary investment.
2. Make the payment: R$ 490 or R$ 790 + options.
3. You will receive a confirmation email with requests (photos, information).
4. The certificate is issued within 3 business days.
5. You receive your certificate by email.
6. If you have chosen the "certificate with promotion" option, we will set a price with you and start promoting the item.

The process is 100% remote.

⚠️ You can request certification directly. However, we recommend a pre-assessment to confirm the item's potential and verify if investing in a certificate makes sense for your case.

Important

✔ Professional certification is a distinct documentary service from preliminary assessment.

✔ The conclusions reflect a specialized professional opinion based on the elements provided by the client at the time of analysis and do not constitute an absolute or definitive guarantee of future authenticity.

✔ Sales are not guaranteed, nor are the timeframe or final value. Market variables are numerous. However, we keep in contact with you, adjusting the strategy when necessary, with the aim of completing the sale.
