bu幣 - 白俄星座(得奬嘢嚟架)

uncirculated幣, 即係唔係流通貨幣, 其實收藏幣方面, 隻隻都唔係流通架啦, 咁即係話, 不流通就係收藏幣方面嘅最基本(最低)完成度. 但uncirculated係grading方面都有分好多唔同level.

BU (brilliant-uncirculated) 大槪係MS-60 至 MS-62
Choice BU 大槪係MS-63 至 MS-64
Gem BU 大槪係MS-65 以上

但係BU又唔一定係唔好, 因為好多嘢, 最後都要講design好唔好, 以最近大家都有講嘅白俄星座為例, 其係隻幣係生產咗三種唔同物料嘅成品


Silver, Alloy standard of silver: 925
Weight of coin, g: 28.28
Quality: "uncirculated"
Diameter, mm: 38.61
Mintage, pcs.: up to 25 000


Copper–nickel
Weight of coin, g: 13.16
Quality: "brilliant–uncirculated"
Diameter, mm: 32
Mintage, pcs.: 10 000


Gold, Alloy standard of gold: 900
Weight of coin, g: 15.50
Quality: "proof"
Diameter, mm: 30
Mintage, pcs.: up to 2000

其實隻幣係先造咗bu嘅銀幣, 攞咗奬, 再造隻proof嘅金幣, 點解我會知, 如果你比小小心機, 睇一睇個幣背面嘅年份就知.

哩隻星座幣, 係攞咗2010年俄羅斯嘅主辦單位特別奬, 而且係整個系列得奬. 所以有錢, 可以嚟個全星座宴.

唔好搞錯喎, 得奬係隻銀幣, 因為當時就係因為佢嘅氧化面概念得奬.
