The first chip is possibly a rare chip. £1 denom on back. Ordered but never put into play although subseqeuently may be in use now.
The Hyde Park chips is definitely rare. 7 or 8 known.

$45 shipped for all 4 chips.
Sale will end in TWO HOURS from now.

Easier for me if you email me and hang a 'SOLD' sign if interested.
