Sometimes it's hard to know whether to sell today, or try to hold out for a potentially higher price later.
Here's a calculator to help you decide.
For your most accurate result, use the total amount you've invested in the card (including purchase price, grading, etc).
Don't worry about this specific card, just use your overall average.
For example, if you buy a card and it takes you one week to evaluate, then 5 weeks to grade, and another week to sell, that's 7 weeks.
