The chip on the left is the new B&G generic £1 chip which Grosvenor are using to replace their old coin center chips which dont work in the auto-sorters. A matching £5 was released a year or more ago (I will be offering it in a later scan). The chip matches the style of the regular Victoria chip which was released a couple of years ago shown on the right for comparison.
I only picked up 5 of these so will need to get some more this week. However, order and pay away and then I will have an idea how many I need.
As these will cost me $2.50 to ship they will be $6.50 shipped.
Email me if interested.
