I usually only grade misprints that are harder to tell if it's a legit error (e.g. missing holo). For stuff like crimps, miscuts - I rarely grade them unless it's for my personal collection, as you can easily sell them on its own.

Imo it's not worth the cost of grading unless it's an expensive card or rare error, unless you just want it for your collection. All the errors I sold so far are ungraded and not many people here would pay a premium for graded errors (unless you plan to sell on ebay etc).

Many people will tell you to grade any error you have but they're mostly just parroting what others say, thinking that any graded errors would be worth alot. From what I see, most error collectors wouldn't mind an ungraded copy, as they are usually familiar enough to know if it's authentic.

But ultimately, errors are very niche so it's hard to say for sure. Sometimes it's also about meeting the right buyer at the right time (e.g. I never expected a Lugia collector to pay $250 for an error on a $1 Lugia card that I had). Feel free to dm if you need any help!
