Replica Bitcoin BitCoin Virtual Currency (Gold) This is a replica product with a Bitcoin motif. It is gold-plated and comes in a plastic case. It might be a fun gag gift. Coin size: 4.5cm circumference Material: Metal Comes in a plastic case. I found this item, which I purchased but never opened, and I'm selling it because I have no use for it. Although it is unused, some have black marks on the surface. The second image shows the one in the worst condition.
