Modified Oz $1 with a Western 658.
The knife....
Given to me by my father in a used, but well cared for condition. I don't recall the actual date (let's just say it was a "few" years ago), but do remember that it was his EDC at the time. And was a treasure to me.
The Coin......
In the late '80's I did a couple year "Walkabout" in Australia (almost the entire time in Qld). I returned home with the usual pocket full of change and walking around money. My mother had mentioned many times that she really liked the graphics and art on the Oz money I brought home. On a number of occasions I noticed her carrying around one of my coins as a "worry stone" of sorts. So I had a jeweler add a loop to one, and paired with a rope chain strong enough to handle the weight. She wore it often.
After Mom (& Dad) passed, it was discovered that my sisters had already pilfered most of her jewelry. This was left behind with the many pieces of "costume" jewelry. The only part with any monetary value is the chain. But the sentimental value to me was high. Mostly because I saw her wear it often, even though she had many options to choose from.
