These coins are well-made. The finish on them can be a bit inconsistent from coin to coin (some are shinier, some more dull), but not enough that it's a real problem. Besides, they wouldn't all look identical if minted in medieval times, right? If you're planning on using them for a D&D campaign I recommend buying an extra roll or two of these in addition to the Tavern Starter Set so you don't run out of small denominations, especially you have a large group.
Fantastic! This is amazing, and I'm so proud and grateful this is an Aussie company producing world standard products for my favourite hobby. Started my first D & D campaign in years off to a cracking start with a treasure chest full of these coins :-) Wonderful!
