+1 for loading the MIB.  If you had, you'd have probably gotten
ifPhysAddress OBJECT-TYPE
    SYNTAX      PhysAddress

PhysAddress ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "1x:"

and you wouldn't be trying to print the address as a string
VK> rH"3.6.1.2.1.2.2.1.6.3 = STRING: "$y*
which looks like it's got a carriage return after the *

Add the -Ox option to display the value as a hex string
  snmpget -v2c -c public -Ox localhost .1.3.6.1.2.1.2.2.1.6.3
to see if that is the case.
