Was told this is 800 but cannot find any mark to match and don't even know the country. Any help would be appreciated!

Hi, It is Dutch, the sword mark or small standard mark. The sword mark with numeral fineness 835, used 1953-today
See: viewtopic.php?f=5&t=32028

The mark, left of the sword mark, with the number 20 (?) is a weight indication mark; the weight indication mark shows a number, to obtain the gross/net weight in grams multiply this number with 5.These weight indication marks consist of a series of 20, with the numbers 1 to 20, used 1906-present. 

The maker's mark appears to be: ZZ with a hammer in the middle for; Zaanlandse Zilversmederijen n.v./b.v., registered in the cities of Haarlem & Amsterdam mark used 1920/1990 see:
