is one of three lots that caught my eye from the more than 3,000 lots
offered in the floor and online auction sessions:
2000 Lincoln sent struck on a small-sized Sacagawea
of the oddest and most visually impressive error coins to cross the
auction block in recent memory is this 2000 Lincoln cent struck over a Sacagawea small-sized dollar coin. Graded MS-66
by Professional Coin Grading Service, it sold for $35,250.
errors are popular with collections, but the typical example is a Lincoln cent struck on a Roosevelt dime. On this
head-scratcher Heritage writes, “The first strike was normal, between
Sacagawea dollar dies on a Sacagawea manganese alloy planchet.
Somehow, despite the great disparity of diameter, the coin ended up
between Lincoln cent dies, and was struck a second time. The collar
die was either absent, or unable to rise above the anvil die due to
the large dollar diameter.”
the dollar coin’s date is obscured, since the Sacagawea dollar was
introduced in 2000, both coins likely date from 2000.
dramatic double-denomination error, this 2000 Lincoln cent struck on a
Sacagawea dollar graded MS-66 sold for $35,250 at Heritage’s 2015
Summer FUN auction.
