Thief once got hold of coin which read 250 B.C. so he understood it is an ancient coin and wanted a great price for it and one day he read something that lit his eyes. He saw "We buy BC coins at the rate of 100 \$ per year old starting at \$10,000 for the first year".

How much money can the thief expect.

He can expect \$0 and a pair of handcuffs - no coin would ever have a BC date on it! So the advert would have been posted by police looking for dumb criminals.

I guess it's this way :
Net amount (expected) = \$10,000 + (\$100 *248) = \$10,000 + \$24,800 = \$34,800
\$10,000 for first year and \$100 for each of the rest 248 years. :thinking:

I knew that wasn't the answer that shabbir was looking for

Since the current year is 2009AD and the coin dates back to 250BC.
So the difference in yrs is 2009-(-250) = 2259
And the prize is only for old coins so current year would not yield any money
2259-1=2258
and \$100/year and \$10,000 for first year so... 2257*100+10000 = 235700

hmm, even sp's got the point, that the deals only for BC coins, so 2009 yrs does not make any money

1. He is said to be a thief in the first place.

2. A coin that old must be handed over to archies. If he holds it, he is a double thief then.

Arrest him immediately.

So, it was 249 BC years old.
Because, it was made in 250 BC.
So, it would be 1 year old in 249 BC, 2 yr old in 248 BC .... 249 yrs old in 1 BC.
Now, out of 249 years, for 248 years he would be given \$100/year. And for the rest 1 year, \$10,000.

Am I wrong ?? :disappoin

Not going into the logic of BC naming because for 1 BC he should get \$10k

So how would the people who pressed the coin know it was 250BC?
In 250BC the birth of Christ was a future event whose date was unknown.
Assuming they could have known (worked it out from the Hebrew scriptures, perhaps, as the Three Wise Men might have done), how then would they have known that the calendar would be numbered from Christ's birth year?
Assuming they could have known that, how would they have known we'd get it wrong and Christ was actually born around 6BC, thus making 250BC actually 244BTABOC? (before the actual...)

The only possible explanation is that a coin stamped 250BC is a fake.
