My guess is that the dime went into solution. Dimes were silver which
is very soluble in lead/tin (solder.) This is why there are solder
alloys with 1 to 2 % silver available for electronics, primarily SMT
components which used to commonly use silver terminations, in order to
avoid dissolving the termination when the component was soldered on.
