Memories of 31 June 1997 #1

I was 5 years ago when the handover happened. I got no memory about the event. But I got a personal evidence of it, coins in the special edition of celebrating the establishment of the HKSAR, 1 July 1997. I collected and kept these coins in my piggy bank for years. The total amount of evidence is valued as $84.6.
$0.1 x 7 = $0.7 $0.7
$0.2 x 2 = $0.4 $0.4
$0.5 x 5 = $2.5 $2.5
$1.0 x 12 = $12 $12
$2.0 x 17 = $34 $34
$5.0 x 7 = $35 + $35
$84.6
