Value Of 1988 Bicentenary 10$ Polymer Banknote

This is where Maccas and Renniks come in handy. According to Maccas, it's worth $2200 in uncirculated condition, whereas according to Renniks, it's worth $2450.

The value also decreases depending on how much wear and tear it's had, so if the note has been lightly circulated, then it's only worth about $1250 to $1750. Similarly, if the note has been heavily circulated, then it's only worth about $250 to $550.

Personally, I think $4000 is way too much to pay for this note, even in uncirculated condition, and I would wait until someone gave me an offer of $2500 or less.
