About PBGRADE

Engineered for Preservation.
Built for History.

For over a decade, Planet Banknote has been the world’s leading source for hyperinflation currency. But we noticed a critical flaw in the industry: the holders didn’t fit.

Collectors were spending thousands on the 2008 Zimbabwe 100 Trillion Agro Cheque, only to store it in standard 2.6-inch US currency sleeves. The result? The top 5-8mm of these historic notes were left exposed to humidity, edge wear, and physical damage. The industry standard was failing the collectors it claimed to protect.

Why We Are Different

“We refused to accept ‘good enough.’ In 2025, we launched PBGRADE with a singular mission: to engineer the world’s first premium rigid holder designed specifically for the dimensions of large-format hyperinflation notes.”

Shop Quality Protection

You don’t protect a Ferrari with a tarp.
Don’t protect your 100 Trillion note with a penny sleeve.
Precision Engineering
Unlike generic supply companies, we manufacture our molds to 79.4mm height. This ensures 100% encapsulation for the Zimbabwe Trillion series and Vietnam Dongs.
Archival Science
We use exclusively Safe-PVC technology—high-impact, non-plasticized rigid material that is chemically inert. It will never fog, yellow, or stick to your notes.
Collector Focused
PBGRADE is owned by Planet Banknote. Every product is field-tested on our own inventory before it ever reaches yours.

Things to Know

– Premium Pricing: Architectural-grade PVC costs more to manufacture than generic penny sleeves. This is an investment.
