The $10 and $20 notes are typically worth from twice face value to $100 or more depending on condition, while the $50 and $100 notes are more valuable. $500 and $1,000 Gold Certificates are scarce and we recommend consultation with one of our currency experts if you possess one of these notes.
By the other hand when you leave your unwashed eggs on the counter, notice that they will last up to 4 weeks before they get damaged, if they are stored appropriated. Of course the taste better on the firsts 2 weeks, but you have until week 4 to consume them, this duration will enable you plan better as it is needed.
I've kept them on the counter for a few days, but normally put them in the fridge. I use the freshness test before using them anyway (2 cups of cold water in a bowl with 2 tablespoons of salt dissolved in the water. If the egg floats it needs to be thrown away).
