On a coiney forum near you (and potential bidders) someone called " Roerbakmix" said March 13:

They have added this ‘provenance’ to a coin I sold via them last year, which is now for sale again: https://www.numisbids.com/n.php?p=lot&sid=6613&lot=176
curiously enough, they omitted the real provenance which I provided before: find location, year when it was found, and documents of the registration in the numismatic Dutch database…

Interestingly those details were added before the sale today:

From the collection of a Romanophile;
Ex Roma Numismatics Ltd., E-Sale 93, 6 January 2022, lot 963 (hammer: £700);
Ex Classical Numismatic Group, Electronic Auction 484, 27 January 2021, lot 769;
Found in Limburg, the Netherlands in 2010. Registered in NUMIS under ID# 1154746.

It sold for 400 GBP. The "description" failed to note the condition; under the compact patina (how produced? Chemistry?) seems to be a troublesome powdery layer that has led to flaking at the edges of the flan. The inscription looks odd to me in places. The outline of the obverse and reverse images do not match, what is that odd break in one edge?
