EARLY MEDIEVAL, Anonymous. Denomination: AR Sceatta (Series J, type 85), minted: Anglo-Saxon; 710-725, York Obv: Diademed head right, double strand pearl diadem Rev: A bird on a cross, pellets in field in front of bird and below horizontal bar on the cross; annulets at the ends of the horizontal arms, beaded inner circle Weight: 0.98g; Ø:10.8mm. I was able to track the provenance to 2014, which showed how the patina developed over the last seven years: Gallery 51 (May auction, lot 185, 30.05.2014) iNumis (Auction 42, lot 191, 05.06.2018) The dramatic blue colour, esp. on the obverse, made me a bit suspicious of artificial patination. However, on close inspection, minor dirt deposits are visible, showing the same vibrant colours underneath: This coin is an upgrade for this coin: Show me your coins with fabulous colours!
