# PirateRush OGs
## OG vs Non-OG
Arrr mateys, listen up! Ye may have noticed that there be two types of NFTs in circulation among our PirateRush crew. Some NFTs have a brown wick while others have a golden wick with the trait "OG" labeled as "Yes".
The OG NFTs were given to our original crew members when we first set sail on this journey. They are special because they currently receive a 2x [rev share](/piraterush/utility/distribution.md) and will have the future utility to purchase a rev share upgrade up to 3x using [$NUG](/piraterush/tokenomics/usdnuggets.md) tokens earned by staking. Only OG NFTs will have the ability to upgrade their rev share.
While there may be more future utility associated with OG NFTs, we haven't quite charted that course yet. But for now, keep an eye out for those golden wicks, me hearties!\

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://piraterush.gitbook.io/piraterush/the-collection/piraterush-ogs.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
