@Series B Notes
Most sellers on ebay do not use the grading terms accurately.
Some sellers neglect to mention that a note has been cleaned, even though it may be obvious. A few current ebay sellers (three with active listings today) are likely actively cleaning notes.
Most ebay sellers are sound though.
I had a look at that £100. It hasn't been messed with or washed.
Considering that the face value is 127 Euro, 160 seems ok to me
That tenner you describe is worth just its face value in that condition.
You should ask for a refund, as by ebay rules if the description is not accurate you are entitled to return the item. Your rights of return are also covered by consumer rights legislation.
