Can Someone Clear Things Up A Bit?

[Kain]

I just played through Mines in hard mode for the first and last time (i am just breezing through it to get to V.Hard). In the same room i got two Clubs Of Laconium both of canadines. Later on i also got another two DB's Saber, again in the same room. I also found about 7 Mats and about 6 Grinders. I am definitely not complaining but i just wanted to know if this is usual or not?
