That's a hypothesis amongst others, but it's just that, with essentially no hard evidence backing it up.
And there's counter-evidence (if mostly circumstantial) in that the first known knitted artefacts are from centuries later, to say nothing of knitting spools which they would predate by some 1300 years.
This hypothesis also lacks a lot of explanatory power e.g. why did some of them find (and take) room in coin hoards? Why have they been found all over Gallia, Germania, and Britannia, but not Italia, Hispania, or the Oriens?
> why did some of them find (and take) room in coin hoards?
People who had access to gold used some of it to create jewellery.

Certain types of jewellery can be found in certain regions. This can be attributed to specific trading network or local preferences. I don't know if that could be proven, but makes sense to me.
